Your weak spots
Enjoying the trainer?
It's free to use. If it's helped you, you can buy Rayan a Red Bull to keep the late-night coding going.
Pick the right play for each hand. Graded against your table rules.
Short 20-hand drills. Your results feed into Progress and your weak-spot list.
Keep the Hi-Lo running count as the cards fly.
Hi-Lo counting rules
Start at 0 after every shuffle and keep a running total of every card you see. A positive count means lots of low cards are gone, so the rest of the deck is rich in tens and aces: good for you. A negative count favours the dealer. A full deck always adds up to 0.
Random stop ends without warning, like a real shoe at any moment. Cards removed hides 1–3 cards, like a dealer's burn card: your count tells you what's missing. Target: a full deck in under 30 seconds with no mistakes.
Convert the running count to a true count, then size your bet.
Cards still in the shoe (each block ≈ 1 deck)
True count = running count ÷ decks remaining. Round toward zero.
Strategy for your exact rules, count-based deviations, house edge and bankroll maths.
Cells with a white dot have a count-based play. Outlined cells change at this true count. Click a dotted cell to see it in the Deviations table.
Hi-Lo index plays for multi-deck shoes. Make the play in the "at or above" column when the true count is at or above the index, otherwise the "below" play. Rows greyed out don't apply to your current rules. The drills always use the deviations you have switched on.
Approximate figures for perfect basic strategy (dealer peeks, no resplitting aces). Each rule's effect is a commonly published estimate, added together.
