What’s new

Version 1.2.0 · Updated October 14, 2026

Index plays: learn the Illustrious 18 Basic strategy assumes a neutral deck. Index plays are the hands where the true count changes the right move, like standing on 16 against a 10 or taking insurance. The new Index Plays trainer in Counting covers all 18, plus the Fab 4 surrenders: • Learn: every play in order of value, with its index • Drill: 10 plays with the index hidden, graded and saved • Fab 4: the four surrender plays, for tables with late surrender Indices follow your house rules, including games where the dealer hits soft 17. A clear path for card counting Counting now opens on a six-step path: learn the Hi-Lo values, tag the cards, keep the running count, convert to the true count, bet with the count, then index plays. Your progress so far is already filled in. A better start New to blackjack? Play your first three hands with the coach beside you. Already know basic strategy? Take the 3-hand challenge and see where the chart and the count disagree. Also in this update • The Coach's Deviations lesson is rewritten and links straight to the drill • Home suggests index plays once you're betting with the count • Coach lessons opened from another tab now take you back there • Tag the cards: the table and buttons stay put when the answer appears
