Pirada

Pirada is a single-player puzzle / luck game where the object is to uncover flipped playing cards in a 5 x 5 grid, attempting to get rows and/or columns to add to a total of 21. The cards are randomly shuffled and laid out before each round. You score points based on how many "21's" you get in a round. You may also uncover a grenade instead of a card, which means you'd better click the "Finished" button to end the round quickly before the grenade explodes. It's a simple game with no options available to set, but it plays fine using the mouse as expected.
