Tiles that fall on the battlefield are randomly generated, and sometimes they might form an inconvenient patterns. For example, there would be no available combinations for tiles of a certain type or there would be no combinations involving the spell seal. Such situations may decide the outcome of the battle if there are any limitations (like a limited number of turns). In that case, every turn is too important to waste it by making an inefficient play.
If you can't find a good move, you can try to use the "Shuffle" option. It will randomly generate a new tile field. There's no limit on how many times you can use it per turn, but be careful because every shuffle costs gems.
Generally the shuffle costs 1 gem. But in the Arena and Daily Challenge the shuffle costs increases every time you use it. With every following shuffle in the current Arena or Daily Challenge battle the price goes up to 5, 10, 15 gems, and so on.
Please note that the spell seal will change its place on the tile field but it will always pick a new place where it can be used. Boosted tiles will also change their places.
The "Shuffle" option is available in all types of battles - monsters, Arena, Daily Challenge, etc.
