Mr. Driller

Driller is a real-time puzzle game that relies solely on quick-thinking and a bit of planning.

The gameplay is a combination of Tetris and Boulder Dash : You have to drill down through multi-colored blocks to reach the bottom while avoiding the consequences of reckless drilling; blocks left without a foundation will drop down after a while, potentially crushing Mr.

As the hero's air supply is depleted with time, the player must regularly grab oxygen pick-ups.

Some of the blocks are "X-Blocks", which take a few tries to drill through and take away a large chunk of the player's air if destroyed.

If four or more X-Blocks come in contact with each other, they vanish and leave behind a small blue creature "Chisokojin", which grants 765 points when picked up.

There are two scenarios in the game, the "2500ft" and "5000ft challenge" (called "500m" and "1000m" in the Japanese version), which are five and ten levels long respectively.

Mr. Driller for Sega Dreamcast is currently worth €36.32 loose, €36.77 complete in box, and €80.86 factory sealed. Prices are based on real sales and update regularly on Gamevaro.

Mr. Driller has a steady sales history on the tracked marketplaces, meaning it trades hands regularly and isn't considered particularly rare.

Loose means cartridge or disc only, CIB (complete in box) includes the original box and manual, and sealed means factory-sealed and never opened. For Mr. Driller, loose is €36.32 and CIB is €36.77 — CIB commands a premium because original boxes and manuals are fragile and often don't survive.

The PAL version of Mr. Driller is currently worth €36.32 loose, versus €34.95 for NTSC-U. Regional price differences usually come down to print run size and regional collector demand.
