How to play Numgrove

1. Look at the signs. A + node is the sum of the numbers below it; a × node is their product.
2. Place the pieces. Tap a number in the pool, then an empty slot (or drag it). Tap a filled slot to take the number back.
3. Make every branch work. When the whole tree adds and multiplies up to the number at the top, you have grown it.

Tips

• Start near the top: the root tells you what its children must make.
• Big numbers usually sit under a ×; small ones often pair under a +.
• On Sapling and Ironwood some pieces are decoys. Not every piece belongs in the tree.
• If you fill the whole tree and it doesn't add up, it shakes: find the branch that's wrong and fix it with Undo or by tapping a circle (moves still count).

Scores

Ironwood is ranked: your score is your time plus 10 seconds for every move beyond the fewest possible. Lower is better. Signed-in players appear on the daily leaderboard, which closes at midnight UTC.
