minipoker is an older game i created for a customer years ago.
Now it came to be converted to an onlinegame (and my first game for tablets & smartphones)
It's easy to use:
goal: get all the cash from the computer player
howto: per round change the cards you like by selecting them (or keep all), bet (blind 1, max. 1000) and press the button on the right (the computer pays your bet if you win otherwise he takes your bet)
scoring: nothing, 1 pair, 2 pair, 3 a kind, full house, 4 a kind, 5 a kind
have fun (and drop a note if you like it)
