Cut & Fill
A tactile puzzle game about moving earth and avoiding traffic.
You control a dozer to cut dirt from some cells and fill holes in others. But watch out—vehicles move through the site, and you'll fail if one hits you.
### What You'll Find
**25 hand-crafted campaign levels** ordered by measured difficulty, from simple grading to complex traffic navigation with gated haul roads and accelerating tempo.
**Three difficulty shifts** — Apprentice, Operator, Foreman — let you tackle the same puzzle at your own pace. Slower traffic? Fewer vehicles? Warning cells visible? All configurable.
**Random level generator** (three tiers) creates fresh procedural puzzles and proves they're solvable before you play them.
**Daily challenge** — the same puzzle for everyone, same day worldwide. Build a streak of personal bests.
**Level editor** with instant verification. Create and share custom levels using shareable codes — no backend, no accounts, no hosting bill.
**Time-trial mode** to compete against your own best times per level.
**Hint system** that works out a way forward from your current position, not just from the start. Earn hints by finishing levels at par.
### How to Play
**Objective:** Fill all holes and reach the exit without getting hit.
**Controls:**
- Desktop: Arrow keys or WASD to move, Space to act
- Touch: Swipe to move or use on-screen pad (configurable)
**Game symbols:**
- ▾ Orange pit = hole to fill
- ✓ Green pit = filled hole
- ◆ Dirt pile = push this
- Yellow dozer = you
- 🚗 Vehicles = avoid
**Key mechanics:**
- Push dirt into holes. It drops in permanently—waste a load and you might brick the level.
- Traffic advances one step per your move, including waits. Timing is everything, not reflexes.
- Red cells show exactly where vehicles land next turn (hidden on Foreman difficulty).
- You can only push, never pull. No infinite retries with the same dirt.
