Blackjack

Why this table deals European: on a public blockchain, a face-down card is not actually hidden. Every card here is derived from a VRF value that must be revealed for you to see your own hand — so an American-style hole card, dealt at that same moment from that same value, could be recomputed by anyone the instant the deal was revealed. “Face-down” on-chain would be theatre. So the dealer's second card is never drawn while a decision of yours could still depend on it. It arrives only once nothing you do can be affected by it: at the end of the round, from randomness committed after you have finished, or derived from the value that ended your turn — or immediately, in the single case where your first two cards make 21 and the hand resolves on the spot with no decision left to make. While you still have a choice to make, the dealer's remaining cards have not been drawn from anything yet — there is nothing to leak, rather than something merely hidden. The principle is not “we hide the card”, it is “we never draw a card while a decision could still exploit it”, and it governs the whole table: the second hand of a split likewise waits for fresh randomness instead of taking its card from the split value you have already seen. Keeping the dealer's card genuinely unknown while every card stays publicly checkable is the honest way to do it — and it is exactly how European casinos deal.

What that rule costs you, stated plainly: because the dealer's second card lands last, money you add in the middle of a hand is exposed to it. If you Double or Split and the dealer then completes a natural blackjack, that extra stake goes down with the hand. Only a natural against a natural pushes. The dealer only draws out its hand when a hand of yours is still standing to be compared — bust or surrender and the round settles on the spot, with the dealer never drawing at all.

European rule sets are a house-wide choice here, and roulette is the clearest place that choice pays the player: the wheel here is single-zero, 37 pockets, so the house takes exactly 1/37 = 2.70% on every bet type, where an American double-zero wheel takes 2/38 = 5.26% on the same bets — nearly twice as much, and a straight gain in RTP for the player. None of this has to be taken on trust: the contracts ship as verified builds, so the on-chain bytecode can be checked against the source, and every card can be recomputed from its published VRF value.
