iPhone

Ten missions, four kinds of puzzles, zero coding required. Crack the code, stay off the trace and earn the GHOST rank. Slip into the terminal and break into a chain of secure systems, one puzzle at a time. Decodia is a hacking-themed logic puzzle game. The hacking is all story; the gameplay is pure puzzle solving, so you never need to know anything about computers or code. Every mission is a short break-in with several gates to crack: • Keypad locks: read the leaked clues and deduce the one code that fits them all. • Token forging: overlay circuit fragments until they match the target exactly. • Network rerouting: rotate pipe tiles until the signal reaches every node. • Cipher decoding: turn the dial and decrypt intercepted messages. Collect evidence as you go, so you never have to memorize a clue. Every wrong answer raises your trace; fill the meter and the system rotates its keys. Stuck? Up to three hints per puzzle, always free. Finish missions to unlock the next ones, earn BREACHED, CLEAN and GHOST ranks, and collect 12 achievement badges. Can you clear a mission with no hints, no trace and under the target time? • 10 handcrafted missions in 2 chapters • No account, no ads, no in-app purchases • Plays offline; your progress stays on your device • One-handed portrait play with sound and haptic feedback
