FIXED — BETTING YOUR LAST CHIPS Putting your whole remaining bankroll on one hand used to end the session with "Busted!" the moment you dealt, before a card was played, so a last-chips hand could never win. It now plays out, and the session ends only if you lose it. FIXED — SCROLLED SCREENS AND THE STATUS BAR On Bankroll Tools and Verify System, scrolling no longer draws text through the clock and status bar at the top of the screen.

NEW — VERIFY YOUR OWN SYSTEM Build a counting system in the editor, then find out what edge it actually produces. Verify System (menu → Tools) deals hands against your system — your tag values, your index plays, your bet ramp, your table rules, your penetration — and measures the edge it really produces. A phone can only deal so many hands in a wait you would tolerate, so every result is a RANGE rather than a single number. The range is the honest answer, and it narrows the longer you run. Runs pool, and if you keep running until you like the answer the app says so on the result itself rather than letting you read it as a guarantee it can no longer make. If it still includes zero, the app says so in plain words instead of printing a figure the run cannot support. It also tells you what a tighter answer would cost in minutes, timed on your own device. Run it once and Bankroll Tools picks it up: your measured edge and variance now drive Risk of Ruin, SCORE, N0 and the bankroll breakpoints. Change your system or your table rules and the app marks the old measurement out of date rather than quietly using it. The figures assume you play every hand. Back-counting is not modelled, so a wonging player does better than the number you see. CORRECTED — RISK OF RUIN AND BANKROLL REQUIREMENTS The two constants behind these figures were not two measurements of the same quantity, and combining them the way the app did overstated risk. Risk of Ruin now reads LOWER and required bankrolls read SMALLER. At the default $10,000 bankroll and $100 max bet on Hi-Lo, Risk of Ruin goes from 27.1% to 3.4%, and the bankroll for 1% Risk of Ruin from $35,306 to $13,632. If you recorded figures from an earlier version, they will differ. The new ones are measured — 20 million simulated rounds per built-in system, seeded and reproducible — not quoted. SCORE moves too, from about 49 to about 29 for Hi-Lo, because it is now computed from that same measured pair rather than from the mismatched one. It is consistent with an initial-bet advantage of 1.02%, which is where this game sits: at a 1-12 spread, that advantage and this SCORE are the same fact stated twice. Insurance is now modelled as well. It is a rule of the game rather than a play style, so leaving it out had been understating every system that specifies an insurance threshold.

Built from real player feedback. Some index plays depend on whether you can double — now you can author both. • Set separate index plays for when doubling is available and when it isn't (for example, soft 18 vs. a dealer 2 — double at one count, stand at another) • Cleaner, centered gameplay on iPad and larger screens More to come. Keep the feedback coming.

Your biggest update yet. Blackjack Edge now lets you build and edit counting systems end to end, author deviations without guessing, and train on a more realistic table. • Build your own counting systems — or start from a preset (Hi-Opt II, Hi-Opt I, Zen, Omega II) • Side counts now drive your real count and strategy, not just the display • Author index plays with a plain-English readout of exactly when each one fires • Manage big deviation sets: search, sort, collapse, and duplicate • Realistic discard tray with Estimation Mode for real-casino count practice • Count drills work with any system you've built, not just Hi-Lo and KO • Correct No-DAS pair-split basic strategy • Sharper cards at every screen size Train the math that beats the house.

The biggest update since launch. Built for advanced players who want to push beyond Hi-Lo basic strategy. NEW IN v1.1: • Custom counting systems — author your own (Hi-Opt II, Zen Count, Halves, KO Pro, anything) with full bet ramp + insurance + side-count configuration. Import and export via the share sheet. • Custom deviations — write your own index plays. Bring the canonical I-18 / Fab.4 or your own 274. The strategy chart shows your custom indices as deviation markers; the engine resolves them with full precedence + applies_when filters. • Index Play Drill — practice deviations in isolation, system-aware. • Wonging Drill — practice the mid-shoe entry/exit decision (the third leg of AP-class practice, alongside Count Drills + Index Play). Synthetic shoe scenarios; 4-button response set (Enter / Stay Out / Increase / Hold) keyed to your active system's bet ramp. • Bankroll Tools — Risk of Ruin (Wong PB formula) + SCORE (Schlesinger standardized) + Hours to Double + Variance Band (1σ / 2σ) + Bankroll-for-target-RoR breakpoints (1% / 5% / 13.5%). Pure AP-canon math; no other mobile trainer offers this surface. • Discard tray + Estimation Mode — practice counting under realistic shoe-depth pressure. Slide the cut card; at end-of-shoe the app challenges you to estimate RC + decks remaining. Strict TC tolerance gates at level-2+ systems. • Side-by-side strategy comparison — tap any strategy chart cell, hit Compare, see how your custom system's deviations differ from Hi-Lo at that decision. • Per-system TC rounding convention — floor (Schlesinger I-18 lineage) or truncate (Wong Professional Blackjack lineage). The first mobile trainer to honor this canon split. • Level-2+ strict TC tolerance gate for AP-class users practicing systems like Hi-Opt II + Zen. Plus the usual round of stability fixes, performance polish, and accessibility improvements. Built for the canonical 1-12 spread on 6D S17 DAS shoes, with all reference values cross-checked against Wong's Professional Blackjack + Schlesinger's Blackjack Attack (4th ed).
