Ossify vs Water Sort Offline

Snake, but your tail doesn't follow you. It fossilises where you leave it and becomes permanent wall. You don't die chasing yourself. You get sealed inside everything you've built. THE DIG One world, carved across every run. Death doesn't wipe the board. Your stone stays exactly where you left it, and the next run starts inside the walls of the last one. The dig only ends when the fortress finally closes around you. SPEND LENGTH, OR KEEP IT Length is your score multiplier and your currency. Shed tail to open an escape route, and every segment you drop hardens into one more wall. Stay long, or shed to survive. That's the whole decision, and it never stops being interesting. CARVE GLASS Catch the rhino and charge your own stone. It doesn't break the wall. It carves it into glass: a clear, permanent passage through your fortress. Glass is the only door you'll ever get, so carve it where future runs will need it. BUILD THE FORTRESS THAT BURIES YOU The ending is not a game over. It's the monument: a board you spent every run building, finished the moment it seals you in. THE RECORD A lifetime ledger of every creature you've eaten and every world you've sealed. It only ever counts up. EVERYONE'S WORLDS Share your finished fortress as a link. Your stone becomes someone else's walls, and their dig starts inside your history. Paste a friend's code and build in the ruins they left behind. HONEST BY DESIGN Free. No ads, no accounts, no timers, no gacha. Accessibility settings never cost you score. Nothing personal leaves your phone. Finished boards, likes and dig counts are shared so others can dig your world. Your tail stays behind. Build well. playossify.com
