In Erdös Latino, an abstract strategy game, two players face off, placing numbers (1–5) in a 5×5 square grid. There are five of each number. On your turn, simply place a number in a space on the grid, such that neither its row nor its column contains another instance of that number. There are two ways to win:
Block your opponent from making a play.
When the board is full, be the player who has claimed more columns.
You claim a column when you are the first player to form a sequence of three numbers, increasing away from you.
You can play with several different levels of information to the players:
Random — You blindly draw the tile you must play.
Perfect Information — The tiles form a face-up, shared pool; you take the tile you want.
Mixed — Shuffle the tiles face-down, then give thirteen to the start player, and twelve to the other player.
