Configuration

The Settings Menu
has several possibilities to change its behavior. All options can be changed from the menu Settings.
The options will be saved automatically.
Settings Size 	In the sub-menu Size you can change the number of tiles on the board. The more tiles you have, the harder (and longer) the game will be.
Settings Speed 	The sub-menu Speed sets the time for the tiles to disappear when connected correctly.
Settings Level 	Choose your game skill in the sub-menu Level.
Settings Gravity 	Checking this item makes the game even harder: If a tile is removed, all tiles lying above it will fall down one step.
Settings Disallow Unsolvable Games 	If this menu-item is checked, only solvable games will be created when a new game is started. Note: You may still choose the wrong way and have to try again if you didn't solve the game, but if it's checked, the game will be solvable.
