A GTO (Game Theory Optimal) solver computes the mathematically best decisions in poker spots — when to bet, how often to bluff, what hands to call with. Serious players study with one. Casual players don't need one to enjoy poker, but anyone curious about the math underneath the game can poke around for free here.
They're free and open. The GTO solver here is wasm-postflop, an open-source engine that produces results essentially identical to PioSOLVER ($1,500). The pot odds calculator does what every paid 'poker odds app' does. We're not building paid alternatives — we're putting the math in everyone's reach.
Rolling out one at a time, no hype, no pre-orders. The order is roughly: equity calculator, ICM calculator, preflop hand chart, basic strategy chart for blackjack, then guides. Check back, or follow us for launch announcements. We'd rather ship one good tool than ten half-finished ones.
Yes, please. Drop a note through the Contact page or post on the forum. The 'Coming Soon' list isn't fixed. If 50 people ask for the same thing, it jumps the queue.
