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: • Code locks: read the colors of earlier wrong tries and deduce the code. • Token forging: overlay circuit fragments until they match the target exactly. • Network rerouting: rotate pipe tiles until the signal reaches every node. • Word locks: guess the hidden word; the colors show how close you are. • Word hunts: find the words of an intercepted message hidden in a letter grid. • Infiltration: step past turning cameras and reach the exit unseen. • Code probes: read the scored guesses and name the hidden symbol code. • Firewalls: slide blocks out of the way to free a trapped packet. • Signal maps: rebuild hidden pictures from row and column clues. • Uplinks: wire numbered servers together with straight cables that never cross. • Laser locks: flip mirrors until the beam lights every receiver. • Frequency jamming: give linked transmitters different channels. • Data push: shove data blocks into the shredder slots, one step at a time. • Circuit tracing: solder one unbroken trace through every pad on the board. • Data sorting: move packets between stacks until every symbol has a stack of its own. • Checksums: fill digit grids until every row and column adds up to its total. • Alibis: match suspects to their login times from a handful of clues. Side jobs branch off the map with puzzles of their own: binary grids, logic-gate locks, packets sliding on ice and trap scans. Every wrong answer raises your trace; fill the meter and the system rotates its keys. Stuck? Up to three hints per puzzle; the first is always free. Finish missions to unlock the next ones, earn BREACHED, CLEAN and GHOST ranks, and collect 30 achievement badges. Can you clear a mission with no hints, no trace and under the target time? • 60 handcrafted missions in 12 chapters, plus 4 side jobs • 21 kinds of puzzles, all solved by logic, never by guessing • Free to play: energy for new missions refills over time, and Chapter 1 and replays are always free • No account; one optional purchase removes all ads and gives unlimited energy • Plays offline; your progress stays on your device • One-handed portrait play with sound and haptic feedback • Play in English, German, French, Italian, Spanish or Turkish
