Spark is an entertaining strategy game (similar to Catrap, Boulder Dash, etc.) for masterminds. You navigate your character on a field (29x18 elements), which consists of ladders, walls, stones and grass. It's your objective to collect all the diamonds. Thereby you have to consider the following: The walls can't be traversed by the character. But the character is allowed to stand on the wall. The stones can be moved, but only one at a time. The ladders can be reached from all directions. The grass can only be removed from the sides or top down. Your character can move in all 4 directions (using the mouse or the arrow-keys). The character has no opportunity to jump. When you are trapped with your character, you are forced to restart the actual game level. Moreover the game possesses a level editor which allows you to create your own fields. The license version of Spark consists of 51 playable and 149 editable level. In the trial version you can enjoy the first 10 levels and edit the level 52.
