Coilkeys

Coilkeys is a 3D tower-drop game that runs in your browser. In a tall, phone-style column a ball of music notes bounces down a tower of piano-key platforms while you turn the tower.

How to play

1. Press the play button on the start screen and pick a level from the grid.
2. A ball of music notes bounces on the top platform of a tall tower.
3. Drag left or right with the mouse or your finger to turn the tower.
4. Line up a gap under the ball so it drops down to the next platform.
5. Reach the bottom to see level complete, then move on to the next level.

What you see on screen

• Top left: the level number.
• Top right: a home button that goes back to the level list.
• Middle: the ball and the round platforms with white and black piano keys; some sections are red.
• Level list: a grid of 45 levels.
• Start screen: the title and a play button on a changing background color.

Tips

• Keep turning the tower. In two games without a drag, the ball was still on level 1 after 60 seconds.
• Drag in both directions: in our tests, alternating drags finished level 1 in two of three games within 110 seconds.
• Look for the next gap before you drag, so each turn is a short one.
• Read our helix tower tips for the numbers behind these tips.
