GiiKER is a minimal color-code deduction puzzle. The game secretly picks a 4-symbol code from 7 colors — your job is to figure it out. Each round you submit a guess, read the feedback, and narrow down the answer with logic. Solve it before your attempts run out. Simple to learn, hard to master. TWO FEEDBACK MODES • Beginner — a colored bar under each slot tells you exactly how that symbol scored: right spot, wrong spot, or not in the code. • Classic — a summary of clues for the whole row, without revealing which slot is which. A pure test of deduction. ADJUSTABLE DIFFICULTY • Allow or disallow duplicate colors • Choose how much history you can see • Beginner, Standard, and Hard presets BUILT FOR EVERYONE • Display symbols as colors, numbers (1–7), or both — no one is left out by color alone • Clean, tactile controls with a signature drag-to-pick color selector PLAY ANYWHERE • 100% offline — no account, no internet, no ads tracking you • Your scores stay on your device No sign-up. No clutter. Just you and the code.
