A free card counting trainer that counts a real 6-deck shoe and tells you the exact EV of every inde

I built a card counting trainer and would like this forum's feedback, since the people here will know what's missing: casinogamessimulator.com/blackjack/card-counting
What it does:
Deck countdown. 1, 2 or 6 decks, one card at a time or in pairs, timed or at your own tap, with Hi-Lo, KO, Hi-Opt I, Hi-Opt II, Omega II, Zen or Wong Halves. The goal is the usual one: a deck in under 30 seconds with the right count. Your times stay on your device.
The count at the table. The blackjack trainer deals a real six-deck shoe to a cut card at 75% and shows the running count, true count and decks left under the felt, counting only the cards you can see; the hole card joins the count when it's turned. A quiz mode hides the numbers and asks for the count between hands. With the Hi-Lo count on, the strategy coach follows the Illustrious 18 and Fab 4 and labels the play as an index play: open the trainer with the count on.
True count and index play drills. The first gives a running count and the decks left and asks for the true count. The second gives a hand, the up card and the true count (six decks, S17) and, after you answer, shows the exact EV of every play for those cards against a shoe standing at that count. The EVs come from a finite-shoe combinatorial analysis of the exact composition, not a simulation. For example, at +6, insurance is worth +0.029 per unit over declining; at +8, splitting tens against a 5 is worth +0.183 over standing.
The index table. Each of the Illustrious 18 and Fab 4 with its published index, what basic strategy does instead, the deviation's gain three points past its index, and the count at which the engine finds the two plays crossing. Most crossings sit within half a point of the published index; a few stiff hands against high cards sit 1.5 to 2 above, and the note under the table says exactly what was computed.
A 30-day program, one task a day, from a first deck countdown to six decks counted right in under 150 seconds, through the true count and the index plays. Progress is kept on the device, or on an optional account.
A daily shoe, casinogamessimulator.com/blackjack/daily-shoe: a six-deck shoe seeded from the date, the same 20 hands for everyone, one unit a hand (6D H17 DAS LS), scored on net units and basic-strategy accuracy against everyone's results for the day. The server replays your actions, so a score can't be posted without playing it.
The basic strategy underneath is the engine's own: 26 rule sets, within 0.005 points of the Wizard's house edge calculator on the 22 I test against it. The approximations, mainly around resplits, are listed on the methodology page.
Free, no sign-up, virtual chips, no ads and no affiliate links. The engine is open source (MIT) at github.com/casinogamessimulator/engines. What would you want next? A bet spread drill, counting leaderboards for the fastest accurate countdown, and a win-rate calculator (rules, spread and penetration in; win per 100 hands out) are on my list, in no particular order yet.

Spanish 21?
May the cards fall in your favor.

Good one. It's not in the engine yet: the 48-card deck is easy, but the bonus payouts and the card-count-dependent strategy need real work. I'll add it to the list.
