1. Your goal
Each level is a logic puzzle. Your goal is to clear the game board using your inventory contents. Pick elements from inventory one by one and place them on the gameboard cells.
2. Combining elements
To clear elements from the game board you need to arrange them in different combinations. For example, simple Orbs will explode in lines of 3.
3. Organizing chains
When elements explode, other nearby elements may shift to neighboring cells, thus setting off a new explosion. Use this behavior to organize chain reactions.
