Cache Across Southern California 2026
Greetings gamers! Are you ready to explore video games through the ages? Find and locate one of the roughly 50 CASC geocaches across all 10 Southern California counties. As you find geocaches, you may stamp your passport to track your progress and turn it in at Signal's Island in San Diego to redeem your prize(s)!
Do not remove the stamp from the container, it is part of this geocache!
How do I use the CASC Passport?
Use the stamp in each CASC geocache and stamp any of the 25 small game tokens on the front page of the passport. At the bottom of each coin, write the GC code of the geocache that corresponds to the stamp provided. Then on the reverse side, circle or highlight the caches you found from the list. Doing these steps will increase efficiency and line management at Signal's Island.
CASC Prize Redemption
To qualify for prize redemption you must bring your completed passport to Signal's Island Goes M*A*S*H (GCBGC72) in San Diego on Saturday, October 3rd 2026.

Tetris
If you’ve ever felt an unreasonable burst of pride from lining up a stack of blocks just right, then congratulations: Tetris already has its pixelated claws in you. Born in 1984 when Russian programmer Alexey Pajitnov apparently had too much time and not enough graphics, Tetris started life on a Soviet computer that could barely run a screensaver. Yet somehow, from this humble pile of falling quadrilaterals, a global obsession was born—proving that you don’t need explosions or dragons to make a legendary game, just gravity and anxiety.
By the late ’80s, Tetris had spread faster than a mis-rotated Z-piece ruins your entire game. Things got truly wild when Nintendo bundled it with the Game Boy in 1989, instantly turning every school bus and airport terminal into a competitive puzzle arena. The game was so addictive that scientists named a real psychological phenomenon after it: the Tetris Effect—that thing where you close your eyes and still see falling blocks. Not dangerous, just mildly concerning…and maybe a sign you should go outside.
The behind-the-scenes drama of Tetris could easily fill a Hollywood movie plot (and, to be fair, actually has). Companies from around the world fought over publishing rights, deals were made behind closed doors in the middle of the Cold War, and the only constant was that Pajitnov wasn’t getting paid. Eventually, he did—thank goodness—and went on to watch his little side project become one of the highest-selling games ever. Not bad for something made with shapes kindergarteners could draw.
Tetris has since shown up everywhere: in arcades, on calculators, on scientific research papers, and even on a Game Boy carried into outer space by a cosmonaut—making it the first video game to orbit Earth without glitching. And now here you are, hunting a geocache inspired by those same falling blocks. Consider this your very own “Level Clear.” Just try not to hum the theme song for the rest of the day. (Spoiler: you absolutely will.)
