Geocache Description:


CHJ has placed this cache for The Fall Fun Days Event in conjunction with the Genesee County Parks.  Please use care when Opening these caches as they are NOT indestructible.  Please sign the log and replace cache as you found it for the next person to find. 

Thank you Glow Mo for creating this cache.

Open the box Using 0510 as a combination.  In front of you is a Tetris game with all the straight yellow pieces permanently attached to the board.  Your job is to take out all the other pieces and fit them around the yellow pieces to completely fill the board without any leftover spaces.  Use this to solve for the red lock combination. Please do not try to pull the yellow pieces off the board.  Ensure the RED lock is on the inside and the black lock is on the outside when you are finished.  I hope you have as much fun solving this puzzle as I did building it.
