The shoe
1 deck — 52 cards per shoe.
Pace
Quiz every 10 cards — about 5 checks per shoe. Lower card speed is harder.
Difficulty
With the running count shown you can check yourself card by card; it is hidden during a count check either way. The true count is the running count divided by the decks remaining.
Sound
A short flick as each card is dealt. Synthesised in the browser, so it works offline and downloads nothing.
