Short Deck Poker Odds Calculator
Explore Short Deck odds for two to ten seats under a reduced-deck model. Choose at least one known Exact hand, then mark any unknown opponent as Random hand so it is dealt uniformly from the legal 36-card deck. The calculator measures 6+ Hold’em equity using A-6-7-8-9 straights and a flush-above-full-house ranking, with full board enumeration when feasible and reproducible seeded simulation otherwise.

Why Short Deck Odds and Hand Rankings Change
Removing ranks two through five changes the sample space. This site also uses a flush-over-full-house ranking and the A-6-7-8-9 low straight.

A-6-7-8-9 is a nine-high straight
A smaller deck changes the sample space
Removing ranks two through five leaves 36 cards. Draw density rises, paired boards appear differently, and familiar standard-deck intuition cannot simply be reused. The picker blocks unavailable ranks before calculation.
The two rule changes scored here
An ace may play below six in A-6-7-8-9. A flush outranks a full house. Straight, flush, and full-house tie breakers still compare the relevant high ranks without using translated hand names.
Using a random hand in the 36-card deck
Exact hand keeps the two Short Deck cards you select. Random hand samples an opponent uniformly only from the legal six-through-ace cards that remain after Exact hands and the board are removed. Every random player and every missing board card uses the same 36-card deck without replacement, so blockers change the available combinations immediately.
Uniform random does not mean a realistic calling or raising range. It is useful for a neutral 6+ Hold’em baseline, especially when comparing one known hand with an unknown seat, but it assigns the same probability to every legal remaining combination. Choose a weighted range tool for opponent-specific assumptions and keep the seed when you need to reproduce the Short Deck simulation.
Confirm the table rules
Short Deck games sometimes vary on trips versus straight or ante structure. This calculator uses the displayed ranking only. Confirm the actual game rules before reviewing a hand.

On a completed board where both are possible, the flush wins under this published 6+ rule set.
Frequently asked questions
Why are cards two through five missing?
Short Deck uses a 36-card deck containing only six through ace.
How does Random hand work in Short Deck?
The simulation deals two legal six-through-ace cards from the shared remaining deck after Exact hands and board blockers are removed. It never introduces ranks two through five or duplicates a physical card.
Does an ace connect to a six?
Yes. A-6-7-8-9 is the special low straight in this ruleset.
Does a flush beat a full house here?
Yes. The category order used by this page places flush above full house.
Can I reproduce a simulation?
Yes. Keep the same hand modes, cards, board, iteration count, and seed.
