Read the grid
The board appears labelled A–F down and 1–6 across. White dice mark fixed coordinate positions. Reading that space — understanding what the dice block and what they leave open — is the entire game.

What is GridlockDice?
Drag colourful polyomino blocks onto a grid, filling every empty cell. But fixed white dice — each stamped with a coordinate like A3 or C1 — sit immovably in your path and reshape every puzzle.
No two dice placements are alike. From level 21, tap any piece to rotate it 90°. The same pieces, completely new geometry.
Mechanics
Quick onboarding tutorials cover the rules in under a minute. The depth only reveals itself as you progress.
The board appears labelled A–F down and 1–6 across. White dice mark fixed coordinate positions. Reading that space — understanding what the dice block and what they leave open — is the entire game.
Colourful polyomino blocks sit in a scrollable tray below the grid. Drag them into position. A green glow confirms a valid fit; red means it won't go. Haptics respond to every placement, error, and solve.
Cover every empty cell and the puzzle resolves — checkmark, star rating, your time. A progress bar tracks your path from level 1 to 50. No timer pressure, but the clock is always visible.
Who this is for
You download a promising puzzle game. Within minutes there is a full-screen ad, an energy bar counting down, or a subscription wall.
GridlockDice was built differently. One purchase. Zero ads. No energy bars. No data tracking. 50 hand-crafted puzzles that respect your attention and your privacy.
Features
One purchase, no gating. Every feature and every level unlocked permanently.
Fixed white dice mark specific coordinates — A1, C3, F5 — and sit immovably in the grid. They replace generic blocked-cell patterns with spatial logic grounded in the coordinate system.
Levels 6–50 are procedurally generated, but every one is verified by a backtracking solver before it ships. If it's in the game, at least one valid solution exists. No unsolvable puzzles, ever.
From level 21, tap a piece in the tray to rotate it 90°. Four orientations, one touch. It layers geometric depth into the core mechanic without changing how the game fundamentally works.
The hint engine runs the built-in solver in real time and highlights the next best placement. Auto-solve completes any level instantly with animation. Both are always available — no strings attached.
Built entirely in SwiftUI and SpriteKit. Spring animations, precise haptic feedback, full VoiceOver support, reduced motion, and dynamic sizing across every iPhone and iPad model.
No SDKs, no trackers, no analytics. Pure Apple frameworks only. 127 automated tests ship with every release. The binary is lean, behaviour is predictable, and your data never leaves your device.

The promise
GridlockDice was built for people who are tired of games that treat players as monetisation targets. It's a tool for thinking — nothing more, nothing less.
No banners, interstitials, videos, or rewarded ads. No advertising infrastructure in the binary. The game earns its living through one honest transaction, then leaves you alone.
One payment unlocks all 50 levels permanently. No monthly fees, no daily limits, no energy bars, no wait timers, no forced pauses. Play on your schedule.
No account required. No data collection, no analytics, no telemetry, no push notifications. Nothing phones home. Your play session lives entirely on your device.
Full VoiceOver support. Reduced motion respected. Haptic feedback that assists rather than distracts. Dynamic type sizing on iPad. Built for everyone, not just the default user.
Every procedurally generated level passes a backtracking solver before shipping. No unsolvable puzzles, no dead ends by design error. Automated tests run before every release.
