GridLock Numbers

How to Play

Choose your grid and fill it out completely with numbers—only if you can.

Start anywhere with 1 and continue filling numbers following these two move constraints:

Turn on the switch under the grids to see all possible moves.

You can undo your moves by tapping on the last number placed.

Each number earns 10 times its value.

Removing a number deducts an extra 1 point.

‘x2’ cells double the added numbers.
