Stacker Game is a Skill with Prizes game billed as a successor to crane games.
In the game there is a row of three cubes which move side to side on the screen, at the first row. When the player pushes the start/stop button, the row of squares will stop. Then, another row of three moving squares appears above the previous row, moving faster than the one before it. If the squares do not align directly above the previous set, any overhanging squares will be removed. If the player misses completely, the game is over. The number of available squares is automatically reduced to two, then one, during the game. The goal is to consistently get the squares directly above the previous set, "stacking" them to the minor prize and ultimately major prize levels. A major prize is worth about 100 times the cost per play.
It is very easy to learn and play. As all that the players have to do is to pile up the blocks to reach the top from the bottom; however the tricky part is for each pile, the speed becomes just a little faster, one block off the pile and the rest become crushing down.
The payouts include minor prize and major prize, which can attract different players. Once the players reach the minor prize level, they will choose between to get a minor prize or to continue to play on for the major prize; almost all of the players will try to the major prize level.
