Small on top, big at the base. First tower in order wins.
1You and your rival each get ten bricks, numbered 1 to 60, in a random order.
2On your turn take the open brick, or draw a hidden one. Tap a brick in your tower to swap it in; the old one goes on the open pile. Don't like a drawn brick? Toss it.
3Bricks out of order stick out crooked. Straighten the whole tower, smallest on top, and you win. Three numbers in a row (like 21, 22, 23) pay extra.
