Anomaly: Logic Puzzles

Something aboard is off.

Anomaly is a deduction puzzle in the tradition of Einstein's riddle, dressed as a mystery on a research station in orbit. One grid, a log full of gaps, exactly one solution — and no luck involved.

NEVER A GUESS

Every case is built so that each step can be forced. There is exactly one solution, and a path to it that needs no trial and error. If you are stuck, you have missed something — you have not been unlucky.

SIX DIFFICULTIES

From introductory to extreme. The next one opens once you have solved three cases of the current level, at least one of them without a hint. Grids grow from 3×3 to 6×5.

DAILY PUZZLE

One case a day for everyone, with its own streak. The week is a ramp: easy on Monday, extreme on Sunday. It is never locked — full version or not.

HINTS THAT EXPLAIN

Three stages: which log entry carries now, which cell follows from it, and finally filling it in. You pay for the look, not for the depth. Hints come from three pools — a daily allowance, the credit that solved cases earn, and purchased packs. They are spent top down: first what expires anyway, last what cost money.

CONSISTENCY CHECK

Is there a contradiction anywhere? The answer is exact — and limited for exactly that reason, with a cooldown instead of endless asking.

BILINGUAL AND ACCESSIBLE

German and English. Dynamic Type up to the accessibility sizes, VoiceOver with spoken forms of every condensed value.

WHAT THE GAME IS NOT

• No advertising, no tracking, no analytics, no advertising identifier

• No accounts, no registration, no server — the game runs entirely offline

• No subscription

• No energy meter that refills, and no waiting time you can buy away

PURCHASES

The full version is a one-time purchase. It unlocks "Hard", "Very hard" and "Extreme" in free play, plus the note sheet and your own crew names. Hints are not included — they cost the same with the full version as without, and are sold separately. Every case remains fully solvable without the full version.

Emergency Lighting is a separate purchase and likewise not part of the full version: a second lighting that bathes the station in red. It changes nothing about the game. The classic one stays available to everyone, and you can switch as often as you like.

Purchased hint packs are consumables and stay on the device where they were bought; the game keeps no account. The full version, by contrast, belongs to your Apple ID and can be restored.
