Gauss Cannon tile for the game Hextraction by Zach Freedman. To use the tile, prime it by inserting two balls on one side of the magnet in the direction you want to launch. This tile only works once so after it is used you can use it as a trap or destroy the tile after it has done its thing.

You can also put 3 extra balls on one side instead of 2 so if you get rid of the trigger ball the tile can be used again right away
