Stacker

The arcade game Stacker is a redemption video game with game play similar to the Commodore 64 game of the same name. Like it's C64 counterpart, rows of blocks three wide move left and right on the screen and you press a button to stop them so as to create a tower. The difference, here, is that, after three levels, even if you make no error, you are reduced to two blocks wide. After another three or so levels, depending on the machine, and you are reduced to one block until the end of the game. You win a prize at the minor prize level. You can stop there or press on to the major prize level to win a bigger prize. If, at any time, you miss the stacking, you lose one or more blocks. When all blocks are gone or you reach a prize level and accept a prize, the game ends.
