Not baqd, not bad. Nice, simple graphics, but there is a problem with the rules. It said four fives, I called BS. It was revealed there were five fives. This means that it IS BS. You're saying there are four of them, not at least four.
Sounds picky, but there is a difference. That's how the game is played. If there are more or less of the number you called, you lose if called on it, as in the above example. Besides that, it is good.
