Do you want to be a hammer master who can fix anything? Then you need good nail skills. Hammer Master is a colourful practice session to train them.
Slide to move the hammer left and right. Drive in all the nails that match the hammer's colour. Hitting nails of a different colour earns you nothing. When your energy bar is full, you unlock a magic ability that gives you more hammers, so you can drive in even more nails. Do not hit the rocks, or the game is over. At the end, count how many nails you have driven in.
