Hacker Logic & Cipher Puzzle.
Race another operator to the same code, or play a standoff where each of you sets the code the other has to break. Stake your credits — the winner takes the pot.
Assemble mining rigs, expand your vault, and run overclocks. Your network keeps earning credits while you are away.
Join a syndicate, claim territory on the map, and take your share of the pot that every raid feeds.
Break into a rival operator's grid and take what they left unguarded — then set your own defenses before they come for you.
Use advanced tools like Logic Analyzers, Time Warps, and Oracle Hints to gain the upper hand.
18 long-run contracts, fresh daily missions, and fifteen ranks to climb on the global leaderboard on the way to Server King.
Version 3.0 turns Protocol 4 from a code-breaking game into a network you run: a new standoff duel mode, a mining empire that earns while you sleep, and syndicates that raid each other for the pot.
Two secrets instead of one — each of you sets the code the other has to break. Turns alternate, and a solve only ends the match once both sides have had the same number of turns, so going first never wins it. Solve on the same turn and the duel is level.
Assemble rigs, expand the vault, run overclocks. Your network keeps mining while you sleep.
Join a syndicate, claim territory, raid rival operators. A share of every raid now feeds the syndicate pot instead of conjuring credits out of nothing.
18 contracts, daily missions, and a rebuilt rank ladder where competitive play finally counts. Reinstalling no longer wipes your progress, and there is a real iPad layout instead of a stretched phone.
Crack a code of all-different digits — alone, or against someone else. Duels work even when your friend is asleep.
