Crystal Castles is an isometric action game developed and published by Atari, Inc., arriving in arcades in 1983 with an Atari 2600 port the same year. Players guide Bentley Bear across a series of multi-tiered gem-filled castles, collecting every gem on each level to advance while evading enemies that grow more aggressive with each stage.
How to Play
Clear every gem in a castle to move to the next. Gem Eaters roam the level stealing gems as they go โ intercept them before they shrink your total. Berthilda the Witch pursues Bentley directly and speeds up as the game progresses; plan your gem route before she can corner you. Honey pots scattered across each castle grant temporary invincibility, letting Bentley run through enemies rather than around them โ save them for moments when multiple enemies block the last remaining gems.

Tips
- Plot your collection path before Berthilda locks on โ doubling back once she is in pursuit wastes the seconds needed to clear a level.
- Honey pots are scarce per level; use them when Gem Eaters and Berthilda converge on the same path rather than spending one on a single threat.
- The arcade original used a trackball; the 2600 joystick handles diagonals differently, so give yourself extra clearance near walls and stairways.
