Marble Run: Music Builder

Drag a ramp, add a bell, press Drop – and the marble rolls, bounces and rings out a little tune.

Marble Run: Music Builder is a gentle marble run game for children aged 3 to 9. In every puzzle a marble dropper sits high up and a cup with a friendly animal waits below. Place the pieces from the tray, turn and stretch them, then watch what happens. If the marble misses, nothing is lost: move one piece and try again.

• Drag ramps, curves, funnels, trampolines, spinners and a portal pair onto the board
• Ring bells and xylophone bars – every note fits, whatever order the marble hits them in
• Watch the marble roll the same way every time, so you can change one thing and see what it does
• Slow the run down or speed it up to see exactly where the marble went
• Stuck? The lamp shows one more piece of a working track as a faint hint
• Land the marble in the cup and earn up to 3 stars: for the cup, for a tidy track and for the notes
