Sequencer (game)

There's a grid of 160 numbers on the left and 30 numbers on the right. Start anywhere in the grid on the left. Selecting a number on the left grid removes it from the right. You may only move to adjacent squares and your aim to clear all numbers from the grid on the right. However, you can't double back on yourself or select a number which has already been eliminated or you lose. Also, the grid on the left follows a pattern, you must do so too! Seven different levels are available.
