Dig A Digit

Merge matching digits up to nine and break the floor. How deep can you dig before the roof caves in?

Dig down through soil, clay, stone, lava and crystal — one digit at a time.

Drop digits into the shaft. Matching digits that touch add up: 2 + 2 makes 4, three 3s make 9. Reach nine and the floor breaks along with everything around it, and you go one layer deeper.

But the ground keeps rising. Every few drops a new row pushes up from below. Let a column overflow and the roof caves in. You have three helmets.

HOW DEEP CAN YOU GO? • Simple rules, real decisions: where to drop, what to save for later, when to break through. • Five layers of earth, each with its own look and its own finds. • Stones never merge. Break them with a breakthrough, a pickaxe or dynamite. • Coins and ten fossils to dig up along the way.

BOOSTERS • Pickaxe — breaks any one block. • Dynamite — blows up a 3×3 area. • Swap — trades the digit in hand for the next one. • Undo — takes back your last drop. Buy them with the coins you dig up.

YOUR DESCENT • A map of everything you have reached: start a new run from any layer of earth you have unlocked. • A daily dig that is the same for everyone, without boosters. • Your deepest layer is your record.
