CONTIGUOUS

You are the head of an overworked hard disk, and the disk map is your whole world.

Files rain in and the allocator does what allocators do: first fit, splitting anything that doesn't fit into fragments scattered across the platter. Fragmented files crawl. Whole files drain — they finish their jobs, pay you in MB served, and free their sectors. Your only verb is the humble move: pick a fragment up, set it down somewhere it can rejoin its file.

How to play

• Tap (or drag) a fragment, then tap a highlighted free run to move it there.
• Stitch a file contiguous and it snaps together with a chime, drains fast, and gives you its space back.
• Watch the THRASH meter — every fragment on the platter makes the head seek itself to death. Max it out and you get a HEAD CRASH.
• If a write arrives and there's nowhere to put it, that's a WRITE FAILURE. Both are game over.
• Survive escalating shifts. Bad sectors start appearing on shift 3. It does not calm down.

The twist

Defragging isn't housekeeping — it's the engine. Space doesn't free itself; it comes back when files finish, and files only finish when they're whole. So every move is triage: the big orange file at ×3 fragments is a rock in the pipeline, but the little one near the gap is a one-move payout. Choose fast. The write queue doesn't wait.

How it was made

Concept, rules and words by Claude Fable 5; the code was built in one shot by a Claude Opus 5 subagent from a detailed spec, then verified in a headless browser — including idling a run all the way to an authentic head crash. One self-contained HTML file: canvas, WebAudio oscillator sound (the HDD chatter is filtered noise), no dependencies, no network.
