LOCKSTEP — a sequencing & ordering logic puzzle for Android
Think in sequence. Satisfy every constraint.
What is LOCKSTEP?
LOCKSTEP is a free sequencing logic puzzle for Android. Every level gives you a timeline of empty sockets, a set of lettered color tokens, and a list of constraints — A before D, C adjacent to D, A exactly 1 from C. Your job: find the one arrangement that satisfies them all.
It's the same kind of ordering and constraint-satisfaction reasoning found in classic logic-grid puzzles and LSAT sequencing games — distilled into a fast, tactile mobile game. If you like brain training that's genuinely about deduction (not reflexes), LOCKSTEP is built for you.

How to play
- Read the constraints — every token is a colored gem with a letter, and each rule names those letters: ordering (A before B), adjacency (C adjacent to D), distance (A exactly 1 from C), and fixed positions (B is at position 3).
- Drag tokens onto the timeline. The puzzle checks your arrangement against every rule.
- Use deduction to lock in what must be true first — the toughest levels chain constraints just like a logic grid.
- Clear the level, earn stars for speed and precision, and keep climbing the 200+ level campaign.
Features
- 200+ handcrafted campaign levels with rising constraint complexity
- Daily challenge with streak tracking
- Endless mode and time attack for high-score chasing
- Achievements and unlockable cosmetics

FAQ
- What kind of puzzle game is LOCKSTEP?
- It's a constraint-satisfaction / sequencing puzzle: arrange tokens on a timeline so that every ordering, adjacency, and distance rule is satisfied at once — similar reasoning to logic-grid puzzles and ordering games.
- Is LOCKSTEP free?
- Yes — free to download and play on Android, with optional cosmetics.
- Does it work offline?
- Yes, every mode plays fully offline.
- Is LOCKSTEP on iPhone?
- An iOS version is coming to the App Store. It's available now on Android via Google Play.
