Every level has a best answer. Serialogic shows you what it is.

Serialogic is a colour sorting puzzle whose shortest solution is worked out in advance by an exact solver, then printed at the top of the screen while you play. The number is a measured fact, not an estimate, and it can always be reached. Finishing is no longer the point: finishing in that many moves is.

WHY IT IS NOT ANOTHER SORTING GAME

Everywhere else in the genre one solution is worth the same as another, so tapping away until it comes good is enough. Here the smallest number of moves is known and announced, which turns a tidying-up game into an optimisation problem. The board also shows you, before you commit, how many tokens each destination would take — the one piece of information the genre never hands over. This is golf, not fumbling.

HOW IT PLAYS, IN FOUR LINES

Coloured tokens sit mixed across vertical columns.
Move the token at the end of a column onto an empty column, or onto another of the same colour.
A run of identical neighbouring tokens travels as a single move, as far as the space allows.
You have won when every colour is gathered in full on one column.

WHAT COMES WITH IT

350 levels across 7 tiers, from three colours on five columns to eight colours on ten. Difficulty climbs inside a tier as much as it does from one tier to the next, so the fiftieth level of a tier is harder than its first.

The first three tiers — 150 of the 350 levels — are proven to hold no dead end whatsoever. Every reachable position was enumerated, not sampled. Above them a dead end becomes possible, so a safety net re-checks after each move that a win is still within reach and tells you the moment it is not. One undo always brings you back.

Undo costs nothing, has no limit and takes away no star: only the moves of your final solution are counted. There is no timer anywhere in the app. A clock beside a move counter would only hurry you along a dimension that measures nothing.

Nine themes in light and dark, six typefaces, forty-four languages, iCloud sync, Game Center achievements and leaderboards.

WHAT YOU WILL NEVER FIND IN IT

No adverts, and there never will be any. No subscription. No account. No analytics, no tracking, no third-party SDK of any kind. Not one network request is ever made: all 350 levels travel inside the app, so the game is entirely offline and plays in Aeroplane Mode, from the first level to the last.

The opening 150 levels are complete and cost nothing. They sit wholly inside the proven range, so a player who has paid nothing cannot get stuck. The other 200 unlock with a single purchase, made once. Nothing renews.

MADE TO BE READ

Six typefaces including OpenDyslexic and Andika, applied across the whole interface. VoiceOver on every column, announcing each token's colour and fill. Dynamic Type. Reduced motion. Token fill — disc or ring — already separates half the colours without using colour at all, and a colour-blind mode swaps green for violet.
