About the game
Tail Recursion is an indie programming puzzle game in which you never steer the snake yourself; instead, you wire up its behavior using connectable blocks, then hit play to see whether your logic holds up. It challenges you to think like a programmer across 70 puzzles, with another 30 said to be on the way. DEV505 both developed and published the game, which has been available since 2026.
