Kookarucha Solver

A GTO solver and trainer for Kookarucha — the double-flop PLO ante game where every seat gets one decision: pot or fold.

The game

Two flops, four to six cards

2–9 players each post an ante and get 4, 5 or 6 hole cards. Two 3-card flops are dealt before anyone acts.

One decision: pot or fold

In seat order, each player pots a fixed bet (players × ante by default) or folds, seeing what earlier seats did. If everyone folds, the last seat wins the antes.

Half the pot per board

Each flop runs out its own turn and river, and each board pays half the pot to the best Omaha high hand — exactly 2 hole cards plus 3 from the board.

Every hand, both boards at once

The matrix groups all 163,185 four-card hands by what they make on Board 1 and Board 2. Each cell shows how often the seat pots (red) or folds (blue), and a click lists every hand in it with its EV.

Solved 6-player spot on K♠9♥4♦ and A♥7♥2♣: a category-by-category matrix for Seat 1, first to act, with pot frequencies and combo counts per cell, and a hand list sorted by EV of potting

Walk the action seat by seat

Click POT or FOLD under any seat to see how the next seat should respond — every seat after every combination of earlier actions is solved.

Seat 4 facing a pot from Seat 1 after Seats 2 and 3 fold: its strategy matrix with the top pair on Board 1, weak pair on Board 2 cell selected at 45% pot, and those 7,245 hands listed on the right

Linear CFR with exact card removal against each opponent. A 6-player four-card solve takes about a minute on a 16-core CPU; 9 players about 8 minutes and 3 GB of RAM.

Five or six hole cards, millions of hands

Switch hole cards to 5 or 6 and the same engine solves the big-hand variants — all 1,370,754 five-card or 9,366,819 six-card hands grouped in the same matrix, every seat and every earlier action still covered.

Solved 9-player five-card spot on T♠T♦8♦ and 9♦8♣7♣: Seat 1's category matrix, first to act, with the all-hands cell selected and all 1,370,754 hands listed by EV of potting

Big-hand solves are heavy — a 9-player five-card solve needs about 23 GB of RAM, and six-card games (up to 7 players) solve for hours. That's what the queue is for.

Queue solves overnight

Snapshot setups into the job queue — or roll a batch of random boards in one click — pick an output folder and press Start. Jobs solve one at a time into board files that reopen in the solver and feed the trainer; Pause parks the running solve, and the queue survives restarts.

The Queue tab after a batch run: five queued 6-player boards solved to 1000 iterations, each written to the output folder as a board file, with Start, Pause and Stop controls above the job table

Train against the solution

Save solved boards to the trainer — or group them into named spots with the exact starting sequences to drill — then answer random hands: pot or fold. Every answer is graded against the equilibrium, with your accuracy and EV lost tracked in antes.

Trainer hand at a 4-player table: under the gun holds the six-card hand A♠A♥8♠5♠4♣3♠ and folds — graded MISTAKE at a cost of 0.19 antes, with the solver's 100% pot answer and the hand class's 76/24 pot-fold split drawn as red and blue bars

After each answer the trainer names your hand's class on both boards and draws the solver's pot-or-fold split as red and blue bars — for your exact hand and for its whole class.
