Decoder Terminal vs GiiKER

A secret cipher of four colored keys is hidden inside the system. You have seven attempts to crack it. DECODER is a code-breaking puzzle — a modern take on the classic Mastermind — wrapped in the aesthetic of a green-on-black decryption terminal. Lock in a guess, hit RUN, and the system reports back: • HIT — right color, right slot • NEAR — right color, wrong slot The hints never tell you WHICH slot is right. Read them, reason it out, and narrow the cipher down before your attempts run out. Crack it in four hits to breach the system. Burn all seven and the cipher stays sealed. NO LUCK. JUST LOGIC. Every cipher is solvable by pure deduction. There are no power-ups, no timers, no ads, no accounts — just you against the code. TWO CLEARANCE LEVELS • EASY · 6 colors — learn the ropes • ADVANCED · 8 colors — for hardened operators Colors can repeat, so don't assume the obvious. BUILT FOR THE CRAFT • A tactile CRT terminal interface — scanlines, glow, and a blinking cursor • Colorblind-friendly: every key carries a letter, never color alone • Honors Reduce Motion • Tracks your stats per clearance level: solve rate, current streak, and best run • Fully offline. No sign-up, no tracking, no nonsense. Read the hints. Breach the system.

Crack the hidden code. 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.
