You are given 28 unlit torches arranged in two intersecting loops.
The torches can slide along the blue loops.
Clicking the arrow in the top right corner moves the torches in the first loop.
Clicking the arrow in the lower left corner moves the torches in the second loop.

Click the fire-gun at the top left to light the top row of four torches.
Click the water-gun at the lower right to extinguish the four torches in the bottom row.

You win once you have lit the torches shown in the right board, but no others.

Variant 2:
In variant 2 the torches in the second loops move counter-clockwise.
Variants 3 to 8 use other target configurations of lit torches.

The solutions to variants 1 and 2 are attached.
