Fair by design

Solved by thinking, never by guessing

Every puzzle has a clear rule and a fair path to the answer. When you get stuck, Quirk helps you see the next step instead of giving the answer away.

  1. Meet the rule

    Each puzzle type starts with a short introduction and a practice board. The rules stay one tap away.

  2. Take your time

    There is no time limit. Undo a move or reset the board whenever you like. Your progress is saved on your device.

  3. Get a nudge

    A hint first shows where to look. Explain this step tells you why, and Use this step can make the move. You earn a hint every three solved puzzles.

A hint on a Bridges puzzle that shows where to look

One certain move

A real Bridges board from Quirk. Each number says how many bridges touch that island. Bridges never cross, and two islands share at most two bridges.

  1. Bridges board with the lower left 3 circled. It already has two bridges to the 5.

    Look

    This 3 already has two bridges to the 5. It needs one more.

  2. The same board with a dashed line up from the 3, crossed out where it meets another bridge.

    Reason

    A bridge up would cross another bridge. The 5 already has its two. Only one way is left.

  3. The same board with a new bridge from the 3 down to the 1 below it.

    Move

    So the last bridge goes down to the 1. Certain, with no guessing.
