// 遊び 02 — DIG DUG, IN THE CLOUD
SUBSTRATA
Dig through the strata, zap the bugs, drop boulders on them.
You are a little drill-bot tunnelling down through five bands of rock, each a different colour. Glitch bugs live in short tunnels of their own, and now and then one phases straight through the rock toward you. You have a short spark beam to derezz them with, and the rock itself to use as a weapon.
It is pixel art on a low-resolution buffer scaled up, so it looks the way a game from 1983 remembers itself. With the page showing, a robot digs toward the nearest bug and zaps it; press play and the drill is yours.
The game takes over this page; Esc or ✕ gives it back. Behind the page, a robot plays it all the time.

On a phone
- Drag to steer: the bot keeps going the way you last dragged.
- Tap to zap.
The rules
- Dig into rock to open a tunnel; the bot moves slower through rock than along a tunnel already open.
- The beam is short and goes straight ahead. Line a bug up and zap it and it derezzes.
- Touch a bug and you lose a life. The counter starts at 3; you are out when you are caught with it on 0.
- Boulders sit in the rock. Dig out the ground under one and it wobbles for a moment, then falls, and flattens whatever is below it, bugs and you alike.
- Kill every bug in the stratum to clear it: that is a 1,000 point bonus, then a new, harder stratum.
- Chips, batteries, drives and crystals are buried in the rock. Dig to one to take it. The deeper it is, the better it is.
Bugs and buried treasure
| Name | What it is | Points |
|---|---|---|
| VIRUS | base points, before depth. | 200 |
| BLOB | base points, before depth. | 300 |
| SPIDER | base points, before depth. | 400 |
| USB · WIFI | the cheap pickups. | 150 · 200 |
| BATTERY | blue, then purple. | 250 · 350 |
| CHIP · HDD | buried a little deeper. | 300 · 500 |
| CRYSTAL | blue, then purple. Rare, and mostly deep. | 800 · 1,000 |
Scoring
- A bug is worth its points plus 100 for each band of rock it was in below the first, plus 50 per stratum you have already cleared.
- A bug flattened by a boulder has its base points doubled.
- If one boulder gets more than one bug, there is a 400 bonus for each of them.
- Clearing a stratum is 1,000.
Tips
- The beam is short and goes straight ahead, so line a bug up along a tunnel before you zap.
- Dig the ground out from under a boulder and step aside: a bug that is below it when it lands is flattened, for double points.
- Never stand directly below a boulder you have just undermined. It falls on you, too.
- Pickups are worth digging for: the deeper one is buried, the more it is worth.
How it ends
When the counter runs out the run ends and a best score is kept. Best scores stay in this browser.
