The direction your chain of elements are created will determine what direction new elements enter the board. Consider this carefully when you are looking for a certain element to match others that are already on the board.
Duels
In duels, try to make large chains of over five items to multiply the collected items and get an advantage. For example, collecting five items in a chain will result in a 2x multiplier, and they will be counted as ten items. Use "Swap" to make even larger chains.
Shuffle
On a level with a lot of "shields" (stone blocks, etc.), use "Shuffle" before your first turn to get immediate access to the trapped bonus objects. Do not use "Swap" too often in normal games. It uses a lot of energy and is needed more urgently during the duels.
Swapping
Use "Swap" to make long chains, but save energy for "Shuffle".
