Fifty missions, sixteen kinds of puzzles, zero coding required. Follow the spark on the map to four secret side jobs. Crack the code, stay off the trace, earn GHOST.
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.
• 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.
Side jobs branch off the map with puzzles of their own: binary grids, logic-gate locks, packets sliding on ice and trap scans.
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; the first is always free.
Finish missions to unlock the next ones, earn BREACHED, CLEAN and GHOST ranks, and collect 28 achievement badges. Can you clear a mission with no hints, no trace and under the target time?
• 50 handcrafted missions in 10 chapters, plus 4 side jobs

• 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
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Side jobs are easier to find: the map now flies over every open side job once, a spark on the map's edge points to the ones out of view, and the result screen offers an open side job after any mission.
