The short answer
A Spin & Go tool is software that gives you solved three-handed hyper-turbo strategy: preflop ranges, ICM and push/fold math, or tracking. Seven are worth knowing in August 2026, and the thing that separates them is whether they handle uneven stacks, because a spin stops having even stacks the moment anyone wins a pot.
GTO Preflop is the one we’d put on your phone: 435 solved Spin & Go scenarios, of which 418 are asymmetric three-player stack combinations, for $119.99 a year. ICMIZER 3 ($179.99/yr) is the pick if you want to build and solve your own spots. SpinSensei is the only tracker written exclusively for spins, and it’s free to everyone until September 1, 2026. FreeBetRange has a real free tier. The other three cover the format well and cost between three and ten times as much.

How we judged them
Four things, in this order.
Does it cover uneven stacks? This is the whole ballgame in a spin and the section below shows why with numbers.
What does a year actually cost? Not the headline monthly rate. The annual figure, since spins are a volume format and nobody plays one month.
Can you use it while you play? Some of these run on Windows only. If you play spins on your phone, that matters.
Is the price attached to a page you can read? Two vendors here make you sign in before showing you a number. We say so rather than guessing.
Why uneven stacks are the thing to check
Almost every free preflop chart you’ll find is an even-stack chart: all three players on 25bb, or all three on 10bb. Real spins are even-stacked for exactly one hand.
We measured how much that matters using our own solve database. GTO Preflop ships 435 Spin & Go scenario files inside the app — 17 even-stack depths from 1.5bb to 34bb, plus 418 asymmetric three-player stack combinations. Decompressing all 435 gives 3,480 decision points and 1,239,784 hand-specific strategies, 917,515 of which are live at a weight above zero. We took the button’s first decision in every one of them and measured how often the solver plays rather than folds.
Hold the button’s own stack fixed at 18bb and the answer moves a lot:
At 18 big blinds on the button, the solver plays anywhere from 30.7% to 46.6% of hands. Same seat, same stack, same blinds. The only thing that changed is what the other two players have. That’s a range half again as wide at one end as the other, and 28 specific hands that go from fold to play: K2s–K5s, Q2s–Q6s, J5s–J7s, T6s, T7s, 76s, 97s, the offsuit kings K4o–K8o, A2o, A3o, Q8o, J8o, T9o, J9o and Q9o.
The action changes too, not only the count:
With even 18bb stacks the button min-raises 31.9% of hands and limps 1%. Put the small blind on 2bb and the min-raise disappears almost entirely: the solver limps 46.5% and raises 0.1%. Put the big blind on 10bb instead and the button starts open-jamming 10.2% of the time, because 10bb behind is the stack that re-jams over a min-raise most profitably.
No even-stack chart contains any of that. It’s the single best reason to pay for a tool that solves the actual stacks rather than a printable PDF.
One more thing our database says, which surprised us: the button’s opening frequency at even stacks is U-shaped. It’s 43.1% at 1.5bb, tightens all the way to 32.4% at 15bb, then widens back to 42.1% at 34bb. The tightest spot in a spin isn’t the shortest one.
1. GTO Preflop — the solved spin tree on your phone
GTO Preflop is a mobile preflop solver and range viewer for iPhone, iPad, Android and Apple Silicon Macs, made by Peka Software. The solutions are computed in advance and ship inside the app rather than streaming from a server.
For spins it holds 435 scenarios: 17 even-stack depths running 1.5, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 15, 18, 20, 25, 30 and 34bb, plus 418 asymmetric combinations down to 1.5bb per player. That asymmetric library is the reason it goes first here. When you double up through the 8bb player and sit down 22/8/3, there’s a solved file for it.
The app is free to download. The standard plan is $19.99 a month or $119.99 a year, and it runs pricing experiments, so the tier you see may differ. It holds 4.8 stars from 240 US App Store ratings and 4.6 from around 3,180 Google Play reviews.
The honest limitation: the built-in trainer, which deals you spots and grades each decision in EV loss, covers MTT at 3–12bb and cash at 50–200bb. It doesn’t drill spins yet. For spins the app is a reference and a range viewer, and a very deep one. If drilling is what you’re after, read our preflop range memorization study for what actually sticks. There’s no postflop here either, by design.
2. ICMIZER 3 — build the spot yourself
ICMIZER is a preflop ICM and Nash calculator that’s been the tournament standard for over a decade. You enter stacks, blinds, antes and payouts, and it solves the push/fold spot. Spin & Go is one of the formats it names explicitly, alongside SNG, SNGMTT and MTT.
That construct-your-own-spot design is what makes it worth the money. A preflop library, ours included, answers the spots someone chose to solve in advance. ICMIZER answers the one in front of you, including the weird payout structures spins throw up when a big multiplier lands and the tournament becomes winner-take-all.
PRO runs $32.99 a month or $179.99 a year, with a 7-day free trial and no card required. There’s a cheaper ICMIZER-only plan at $15 a month less ($80 a year less) that drops the MTT Coach trainer and the replayer. Two add-ons sit on top: NITRO cloud calculation at $179.88 a year, and a mobile version of the coach at $40 a year. Prices exclude VAT.
The catch is that it’s a calculator first. You’ll spend time setting up spots, and the mobile coach is a paid extra on an already-paid plan.
3. SpinSensei — the only tracker built for spins alone
SpinSensei is a Windows poker tracker and real-time HUD written for Spin & Go and nothing else. Hand replayer with GTO range overlays, leakfinder, filters, table management, preflop charts with quiz training.
The pitch is narrow and correct: general trackers carry cash-game and MTT machinery you’ll never open, and they make you assemble a HUD from third-party profiles before the first session. SpinSensei ships pre-configured for three-handed hypers. It auto-tracks PokerStars, Winamax, iPoker, Unibet and ACR, and takes manual imports from GGPoker and Betclic.
It’s free for everyone until September 1, 2026 — that’s a week from now, so grab it. After that it’s €49 a month as a launch price through December 31, 2026, then €69 a month or €662 a year from January 1, 2027. A 7-day trial needs no card.
Two limits worth knowing. Windows only, so Mac players are out. And the GTO solver it advertises is marked coming soon, meaning today it tracks and analyses what you played rather than telling you what to play.
4. FreeBetRange — the best free tier here
FreeBetRange is a browser-based range builder, viewer and preflop trainer covering cash, MTT, Spins, Mystery Battle Royale and short deck. It runs in a mobile browser, which makes it the only non-app option on this list you can realistically use away from a desk.
The free tier is genuinely usable rather than a demo: basic ranges, a limited selection of GTO spots, and 50 trainer hands across 5 ranges per day. Pro at €13.20 a month or €159 a year opens 100,000+ ranges, weighted multi-colour ranges and unlimited trainer practice. Elite at €29 a month or €348 a year adds hand-history upload and opponent-type analysis.
It shows up in our own data too. In the 30 days to August 11, 2026, our Apple Search Ads account recorded installs from players searching “freebetrange” (2), “gtobase” (5) and “snapshove” (3). Small numbers, and floors rather than totals since most of our spend runs through Search Match with no keyword attached, but they say people shopping these names are shopping on a phone.
What you give up is depth of solved spin coverage. It’s a range platform with spins included, not a spin specialist.
5. HoldemResources Calculator — the short-stack solver
HRC is a desktop preflop and postflop solver for Windows, macOS and Linux, and it powers several other study tools. For spins it’s the serious version of what ICMIZER does: you build the tree, it solves it, and you can push the calculation much further.
Classic costs $16.66 a month, $39.99 a quarter or $119.90 a year, and it caps at 30bb effective with a 50,000-node tree limit. For spins that cap is nearly harmless — the format tops out around 25bb at the start and only shortens. Pro at $49.99 a month or $359.90 a year removes the tree limit and adds postflop solving. Both come with a free trial and a 14-day money-back guarantee, and HRC gives away push/fold tables and a Nash calculator for free.
It’s the least convenient option here. Desktop only, no mobile version, and the interface expects you to know what a tree size limit means before you pick a plan.
6. GTOBase — the dedicated spin library, at a price
GTOBase is Simple Poker’s browser application, sold one solution library at a time. The Spin & Go library is one of the five, and it covers 5–30bb three-handed with postflop solutions and a trainer that scores your played hands.
It’s the most complete spin-specific product on this page and the most expensive by a distance: $150 a month, $400 for three months, or $1,200 a year billed as $100 a month. That’s ten years of GTO Preflop Pro for one year of one library. Its iPhone app was last updated in July 2023 at version 2.09, so the phone route is effectively closed.
For a high-volume regular at stakes where $100 a month disappears into rake, it can pencil out. For everyone else it doesn’t. We wrote up the full case in our GTOBase alternatives comparison.
7. GTO Wizard — the generalist
GTO Wizard is a browser study platform with presolved preflop and postflop libraries across cash, MTT and Spin & Go, plus drilling and reports. If you play spins alongside other formats, one subscription covers all of it, and that’s a real argument.
The Starter tier runs about $468 a year, which works out to $39 a month billed annually. Treat that figure as the softest number on this page: GTO Wizard’s pricing page redirects logged-out visitors into the app, so you can’t read a price without an account. Ours comes from our last verified check and their tier announcements. Their direct comparison with our app is in GTO Wizard vs GTO Preflop.
For a spin specialist it’s a lot of product you won’t touch, at four times the price of a tool that covers the format properly.
Which one should you pick?
You play spins on your phone and want the right answer at the table. GTO Preflop, $119.99 a year. The 418 asymmetric configurations are the part nothing else on this list matches at this price.
You want to solve your own spots. ICMIZER 3 at $179.99 a year, or HRC Classic at $119.90 if you’re comfortable with a solver interface and stay under 30bb.
You want to know where your money is going. SpinSensei, free until September 1 and worth installing this week. Pair it with a range tool; it doesn’t replace one.
You’re not ready to spend anything. FreeBetRange’s free tier plus free push/fold tables from HRC. You’ll hit the 50-hand daily trainer limit fast, and that’s the nudge to pay for something.
You play spins and three other formats. GTO Wizard, and accept the price.

Spin & Go tools: FAQ
What is the best Spin & Go tool in 2026?
For most players, GTO Preflop, because it solves the uneven stacks a spin actually produces and runs on the phone you’re playing on, at $119.99 a year. If you’d rather build spots yourself than look them up, ICMIZER 3 at $179.99 a year is the better fit. GTOBase’s dedicated Spin & Go library is the most complete spin product and costs $1,200 a year.
Are Spin & Go tools allowed while playing?
It depends on the room, and you should read your room’s terms rather than take our word for it. The one universal is that real-time assistance — software that computes a solution for the hand you’re in — is banned everywhere. Static preflop charts sit at the permissive end of the range and most rooms allow them, but some sites restrict third-party software during play more tightly than others. Trackers and HUDs are the most room-dependent of all, so check before installing SpinSensei or anything like it.
Do I need ICM for Spin & Go?
Standard three-player spins are winner-take-all, so there’s no ICM pressure in the ordinary case — chip EV is the right model. ICM only enters when a large multiplier triggers a payout structure that pays second and third. That’s why a chip-EV preflop library covers most spin hands correctly, and why an ICM calculator earns its place for the rest.
Is there a free Spin & Go tool?
Three. FreeBetRange’s free tier gives basic ranges and 50 trainer hands a day. HRC publishes free push/fold tables and a Nash calculator. SpinSensei is free to everyone until September 1, 2026, and offers a 7-day trial after that. GTO Preflop and GTOBase’s HU Cash library are also free to start on, with paid tiers above.
What stack sizes do Spin & Go tools need to cover?
Spins start around 25 big blinds and shorten fast, so 2–25bb covers the even-stack case. Uneven stacks are what most tools miss: after one all-in the table can be at 22/8/3 while the “effective” depth looks like something else entirely. Our database solves 418 asymmetric three-player combinations down to 1.5bb per player alongside 17 even-stack depths.
