I'm still unsatisfied after blackjack was removed. I have a solution.

There needs to be no actual game. Just a gani that shows cards of different suits. These suit cards have no numbers and no royals. The next step is to tell the player what they have. No actual game screen. The player would be told some like this: "you have 6." Then it could have options: "draw or fold?" Then the game would proceed like that. Simplified versions could work very well and not require things that would be bad for Era.

Darts could be added too.
