Snake in 10 Lines: Learning More by Coding Less
summary
Claims a complete, playable Snake implemented in 10 lines using only the JDK with Kotlin and Swing, solves raw key handling by reading arrow key codes, reduces state by storing snake as a list of integers with a one-dimensional trick (wraps lines visually), movement as “add head remove tail,” eating by regenerating food with generateSequence, fixes opposite-direction and scoring bugs, and leaves a deliberate “kill screen” when no empty cell remains so the minimal game actually runs and is playable.
