690 route: Use the starting block to explode the bomb next to the 4 blocks on the left, create a wedge allowing 1 block to explode the other bomb. This frees another block, which is used to explode the bomb at (8,4), freeing 3 blocks. These will be used in the top left to free 6 blocks. Use the first one to explode the bomb immediately above the force floor near the start to free 5 more blocks. These blocks will be used to explode the lowest bombs (apart from the bomb by the exit and (25,16)). To explode (23,19), the recessed wall at (20,21) must be used. The last block can be pushed onto the ice slide and pushed into the bomb guarding the skates. Now push the block next to the thief through the bottom part of the level to explode the bomb guarding the exit.
