Observe. Remember. Repeat.
SION: Visual Memory challenges you to memorize patterns and reproduce them before time runs out.
Choose Easy, Normal, or Hard and progress through increasingly demanding rounds. In Hard mode, remember the order in which characters appear and tap them in the same sequence.
FEATURES
• Three difficulty modes
• Increasingly challenging patterns
• Personal best scores and local statistics
• Separate Game Center leaderboards for each difficulty
• Music, sound effects, and haptic feedback
• Pause and resume without losing a life: interrupted rounds restart with a new pattern
Play without creating an account. Game Center is optional and requires signing in to Game Center on your device.
SION is free to download and includes advertising. The iOS version has no in-app purchases or subscriptions.
