9/5 Jacks or Better Strategy and Pay Table
9/5 Jacks or Better keeps the familiar Jacks or Better rules but pays only 5-for-1 for a flush. That one-line change is a useful lesson in why a pay-table label matters before the first card is dealt.

Overview
How this game plays
The hand categories and most familiar decision patterns remain recognizable, while flush draws contribute less. Sharper Edge still rates the game Low volatility, but its configured 98.45% return gives the house substantially more room than the 9/6 table.
The return shown is the configured long-run return at max bet with exact strategy, not a prediction for a single session.

Full pay table and rules
Payouts below are credits returned for wagers of one through five coins. Sharper Edge practice always uses the five-coin maximum, highlighted at right.
| Hand | 1 coin | 2 coins | 3 coins | 4 coins | 5 coins |
|---|---|---|---|---|---|
| Royal Flush | 250 | 500 | 750 | 1,000 | 4,000* |
| Straight Flush | 50 | 100 | 150 | 200 | 250 |
| Four of a Kind | 25 | 50 | 75 | 100 | 125 |
| Full House | 9 | 18 | 27 | 36 | 45 |
| Flush | 5 | 10 | 15 | 20 | 25 |
| Straight | 4 | 8 | 12 | 16 | 20 |
| Three of a Kind | 3 | 6 | 9 | 12 | 15 |
| Two Pair | 2 | 4 | 6 | 8 | 10 |
| Jacks or Better | 1 | 2 | 3 | 4 | 5 |
No wild cards. Minimum paying hand: a pair of jacks or better. Standard play uses a 52-card deck, a five-card deal, one draw, and any hold from zero through five cards.
*The starred royal category returns 250-for-1 below max bet and 800-for-1 at the five-coin maximum. Return and edge shown on this page assume max bet and exact strategy.
Pay-table identity
What makes it different
Same game, one number short. The flush pays 5-for-1 instead of 6, and that single line cuts the return from 99.54% to 98.45% — the house edge more than triples, from 0.46% to 1.55%.
Every other payout line matches the 9/6 configuration. Comparing the two side by side isolates the effect of a single pay-table change without introducing new hand categories or kicker rules.
What to practice
Strategy priorities
- 1Flush draws drop in value because a completed flush pays one credit less per coin.
- 2Do not assume familiar cards always have the same EV; the trainer resolves every close hold against this exact 9/5 table.
- 3Practice the pair of JoB games side by side to make short-pay spotting a reflex.
Worked decision
The same four-flush is worth less
Discard K♦ and draw one card to the four-spade flush.
9/5 EV: 1.021 per coin · the identical hold on 9/6: 1.213.
The correct hold is still the four spades in this deal, but the one-credit cut to the flush payout removes 9/47 of a credit from its average return. Exact strategy is pay-table specific even when the visible cards do not change.
EV is per coin and comes from enumerating every legal draw for this exact five-card deal.
