## What is Slacken?

Slacken is a puzzle of pure spatial reasoning. Each level hands you a tangle of nodes connected by straight lines. Your job: drag the nodes around the canvas until no two lines cross.

That's the whole game. No timers. No move counters. No coins, gems, or energy meters. No predatory ads interrupting every level. Every puzzle is provably solvable by construction, so you never have to wonder whether you've hit a dead end.

— FEATURES —

• 90 hand-tuned levels spanning seven classic graph topologies — wheels, ladders, grids, prisms, antiprisms, triangulated polygons, random planar graphs.
• Endless mode: unlimited procedurally-generated puzzles, deterministically seeded so a given level number always produces the same puzzle.
• A daily challenge — one date-seeded puzzle, the same for every player in the world. Keep the streak alive.
• The Specimen Archive: every first solve files a collectible graph specimen. 56 to catalogue, from common Cartwheels to legendary Delaunay's Dream.
• Personal bests per level — fewest moves and fastest time tracked separately. Beat your own records.
• Three visual themes: the drafting-paper Blueprint, plus Midnight and Ember for subscribers.
• A three-tier hint system for when you're stuck. One free hint per day; more available as in-app purchases.
• Optional ad-free subscription. Cancel any time.
• Designed in the spirit of Threes, Mini Metro, and A Good Snowman: minimal chrome, calm palette, gentle sound, satisfying haptics on every resolved crossing.
• Portrait, single-hand, no internet connection required to play.

— HOW IT WORKS —

Each puzzle is a planar graph that has been visually scrambled. Lines cross where the nodes have been displaced from their solved positions. Drag a node and the lines connected to it follow in real time, turning red whenever they intersect another line. Untangle the graph and the puzzle is done.

— RESPECTFUL MONETIZATION —

Slacken is built around the idea that puzzle players deserve to be treated like adults. Ads are interstitial only, every three levels, and you can remove them entirely with a low-cost subscription. Hint packs are consumable; nothing in the app is gated behind virtual currency, daily logins, or watch-an-ad-to-continue mechanics.

— TECHNICAL —

• iPhone only, iOS 17 and later.
• Portrait orientation.
• English only in v1 (more languages coming based on demand).
• No analytics or crash-reporting SDKs. Crash diagnostics happen via Apple's standard App Store Connect tooling and only if you opt in via Settings → Privacy & Security → Analytics.
