Stack is poker built like a sport. Play ranked 1v1 Duels, climb a real ELO ladder from Donkey to Endboss, and get better every single hand — with AI coaching baked right into the game. Most poker apps make you choose. Casino apps are fun but teach you nothing. Solver tools teach you something but feel like homework. Stack is the one that's both: a competitive poker game you play to win AND improve at the same time. Chess.com built this for chess. Stack is building it for poker. ----- PLAY & COMPETE ----- RANKED 1v1 DUELS — REAL PLAYERS, REAL ELO This is the heart of Stack. Go head-to-head in ranked 1v1 Duels against real players with a live ELO rating. Match instantly or challenge your friends. Start as a Donkey, grind your way to Endboss. Your rank is earned, not bought — every win moves you up, every loss means something. PLAY POKER YOUR WAY 6-max cash, heads-up, and ranked Duels against AI opponents that actually punish mistakes. Jump into a hand in seconds. Blitz mode keeps the action fast. DAILY MISSIONS + STREAKS Show up, play, earn XP, keep your streak alive. The daily loop keeps you sharp and keeps your rank climbing. XP, RANKS & COSMETICS Earn XP for every session, unlock rank tiers from Donkey to Endboss, and personalize your table with cosmetics you earn — not just buy. ----- GET BETTER WHILE YOU PLAY ----- AI HAND INSIGHTS + REPLAY After your hands, get AI-powered analysis showing exactly where you lost EV and what the right play was. Replay the hand and see it differently. PREFLOP TRAINER Drill your preflop ranges until they're automatic. Rapid-fire spots so you stop leaking before the flop. POKER PUZZLES — RATED & RANKED Solve real in-game decisions formatted as puzzles, each with a difficulty rating and a correct answer with explanation. Addictive and humbling. CONCEPTS & LESSONS LIBRARY Short, structured lessons — from preflop fundamentals to GTO concepts — for players who want to understand the game, not memorize charts. ----- WHY STACK ----- Poker should feel like a game you're climbing, not a spreadsheet you're studying. Stack gives you a rank to chase, daily reasons to come back, and AI coaching so you're getting better the whole time you're having fun. Play first. Improve automatically. ----- PERFECT FOR ----- • Competitive players who want a real rank to climb • Players stuck at a stake who know they're leaking somewhere • Beginners who want to learn poker by playing, not by reading solver software • Anyone who finds casino apps empty and GTO apps too dry ----- PRO MEMBERSHIP ----- Pro: $9.99/month or $99.99/year • Unlimited AI hand insights and replay • Full Concepts & lessons library • Advanced ranked Duel modes • All cosmetics unlocked • Priority support Free includes ranked play vs AI, daily missions, Puzzles, and Range Rush. ----- VIRTUAL CHIPS ----- Stack uses virtual chips for all in-game play. Virtual chips have no cash value and cannot be redeemed for real money. All chip purchases are for in-app play only. Stack is a poker game and training app — not a real-money gambling platform. ----- LINKS ----- Support: support@stackpoker.gg Privacy Policy: https://stackpoker.gg/privacy Terms of Service: https://stackpoker.gg/terms

Verdict

The call

The clearest difference is in-app purchases: ICM Calculator at none against Stack Poker's 6. ICM Calculator also leads on iOS requirement (9.0 vs 16.6). Stack Poker's advantage is review sentiment (44% vs 33%) and ratings volume (155 vs 21). On price, rating, ads and device support there is nothing between them.
