Equation Engine

Equations · 30 levels

Shift the number columns until every equation is true.

How to play

1. Tap the side slider (or drag it down) to start. Each highlighted line reads like a sum: 3 + 4 = 7.
2. Tap ▲ ▼ to nudge a column one symbol. Nudges are limited: the counter holds exactly enough.
3. Make every equation true. Later, LOCK columns and use the side slider again: the others shift down by the displayed number.

One nudge can fix one line and break another. Look at all the lines before you nudge.
