Magic Gem

Magic sums · 30 levels

Number the corners so every face adds up the same.

How to play

1. Tap a number, then a dot (or the dot first). Tap a placed number to lift it off.
2. Every line or face must add up to its target. It glows when it's right.
3. Gems are 3D: drag to turn them, or tap ◀ ▶ ▲ ▼. Dots round the back are dim until you turn them to you.

Add up every number and count how many lines or faces use each dot: it tells you which totals are possible and where the big numbers must go.
