This cache was placed on the 25th anniversary of the release of the landmark puzzle video game, Tetris. The name Tetris comes from a combination of tetra (each piece is made up of a different arrangement of 4 blocks) and tennis, the designer's favorite sport. Since its release in 1984, Tetris has consistently ranked as one of the greatest games of all-time, having sold tens of millions of copies and spawned countless spin-offs and variations.

Needless to say, the cache will not be found in the middle of Marshall Lake. To figure out the true coordinates, you will need to play and correctly solve a simulated game of Tetris.

Gameplay: In this game (as with standard Tetris), your goal is to sequentially place each of fifteen given Tetrominos (see attached file) into a 6 x 10 well (6-high x 10-wide) so that no open spaces remain. Rotating the Tetronimos is allowed, but reflection is not. The order the pieces fall is given:

(first) L O T Z * J T * I J * I J Z * S J L * I * (last)

It is up to you to determine which particular piece fits where in the final puzzle (there is only one solution). In regular Tetris, when a row is completed, it disappears. In this puzzle cache that will not happen since you need all the pieces together to get the final coordinates, but when a piece is placed that completes a row, an asterisk (*) is shown to denote that. Furthermore, each Tetromino piece has 4 letters associated with it (see attached image), which when correctly assembled will give the coordinates for the final cache.

NOTE: When rotating pieces, keep the relative orientation of the letters consistent with their original locations, and in the final solution be sure to consider each letter whether upside down, sideways, or rightside up.

Cache is log-lonly and you can check your answers for this puzzle on Geochecker.com.

Finally took a detour on my way home from work to replace the cache container. The coordinates are the same but the placement isn't as elegantly consistent with the cache theme as the original.

Enjoyed the puzzle and solved it without (too) much trouble, but could not find the cache. GZ is very overgrown and full of tumbleweeds, but jacobboulder and I gave a good search. Nada. Fence at GZ has also seen its better days...Would appreciate very much if CO could check on this one. Thanks!

RIP. A hint would definitely help...

I admit I spent most of a late Sunday morning printing out and rearranging Tetris pieces. But I found it extremely satisfying to solve this puzzle after doing so. I had almost no problem solving the longitude part of the puzzle, but for some reason unbeknownst to me, I couldn't quite envision rotating a certain piece essential to the latitude half other puzzle. The brain works in mysterious ways. I eventually figured it out after determining that I almost certainly had most of the puzzle solved and I only had to adjust a very small piece, despite my brains resistance.

Must have missed this game when it first came out - but done it now, thanks to this puzzle.
Glad not to have had to walk too far to GZ in this sunny weather - we're not used to this temperature!
Your warm dry climate must be the reason the log strip felt so new and crispy, despite the many logs on it.
Thanks for looking after it so diligently.
