Babylon (2003)

Babylon is a simple and fast-playing brain teaser for two players.

The game consists of twelve tiles in four colors, and the tiles are scattered on the table at the start of play, creating twelve stacks that are each one tile high. On a turn, you take one stack and place it on another stack that is either (a) the same height or (b) topped by a tile of the same color. Stacks cannot be divided. Players take turns until one player cannot make a move; that player loses the game and the other player wins.

Some versions of Babylon suggest playing a number of rounds, with the first player to win two out of three (three out of five, etc.) rounds winning the game.
