In Dissembler, empty space is your enemy.

This smart little puzzler builds on a familiar concept. Line up three or more tiles of the same color and the pieces disappear. If you’ve played Candy Crush Saga, you’ll understand the basic idea.

But Dissembler adds a twist: Pieces cannot move into empty spaces—they can only swap with adjacent ones. If a tile ends up stranded by itself, you’ve messed up. Time to try again. And again. And again.

Let’s attempt to improve your chances.

First, before you make any moves, look at the board and visualize how you’d like to cluster colors. Patterns often make themselves apparent if you take a minute to consider the full picture.

Second, experiment. There’s no penalty for a wrong move. There’s no timer. And the easily accessible undo button lets you backtrack through past decisions. You’re not expected to miraculously untangle every problem on the first try.

Recognizing mistakes can steer you toward solutions. If you end up with a tile isolated in a corner, you know you’re on the wrong path. Undo the move and try a different approach. Narrowing down options is especially useful as the puzzles get more complicated.

Dissembler shouldn’t be a stressful experience, though. If you can’t solve a puzzle, that’s OK. Come back whenever you’re ready to try again.
