Every puzzle in INFERRA obeys a hidden Law — a secret rule you cannot see. Mark tiles on the board and submit. The Seals answer with a single, merciless number: how many laws your marking satisfied. Never which ones. From that scarce signal you must reason your way to the truth. No tutorials. No hints. No pay-to-win. And because every board is procedurally forged, there are no walkthroughs to look up — only your own mind. THE DAILY TRIAL One shared puzzle for the whole world every day. One attempt counter, one clock, one leaderboard. Your first solve is final — make it count. WORLD RANKS One global leaderboard for the Daily Trial. Claim your name and see where you stand today. THE GAUNTLET A personal campaign that grows harder forever. Your sequence of puzzles is seeded to your device — nobody else can walk your path. ENDLESS Five difficulty tiers, from gentle 4x4 inductions to 6x6 boards ruled by four interlocking laws. Challenge a friend to the exact same puzzle with one link. THE CODEX Twenty families of laws to discover, from The Census to The Weave. Each solved puzzle reveals its laws in plain English and records them in your Codex. Rank ORACLE awaits those who solve a Law on the very first submit. Good luck — you will need reason, not luck. INFERRA COMPLETE (one purchase, forever) unlocks the full Gauntlet, Endless Tiers 4-5, the Daily Archive, and four bonus themes. The Daily Trial is free for everyone, always.
