A game, usually a Puzzle Game or a Simulation Game, in which the player has little to no direct control over the game's events. Instead, the player's task is to "set up" the solution, then hit a "go" switch to activate the solution and see if it accomplishes the task correctly. Setting up the solution may require enqueuing objects with a list of commands to follow, or arranging objects on the game board to change the way they react to one another. If the solution contains elements of randomness or is particularly complex, the player will need to perform many unsuccessful test runs to adjust the solution before finding one that works.
