LAI Games has manufactured its 10,000th Stacker instant redemption game.

Stacker, which was introduced in 2005, was the first instant redemption game on the market to offer both major and minor prizes.

The game challenges players to stack horizontally moving blocks directly on top of each other with each level getting progressively harder.

When the player reaches the 11th level they can accept a minor prize and walk away a winner or continue playing for a major prize.
