Turnbox level 7: the box mid-turn, white balls falling towards the exit

How it plays

Three rules. One finger.

Ten seconds to learn. By the third chapter you weigh every single tap.

The box turning a quarter turn while the balls fall
01 · TAP

The box turns.

Every tap turns it 90° and everything inside falls. Hold your finger down and it turns again each time the balls settle.

A chain of six white balls leaving through the exit in one turn
02 · WHITE

White goes out.

Drop the white balls through the glowing exit and fill the target before the clock runs out.

A red ball in the mouth of the exit, lit by a red warning light
03 · RED

Red stays in.

If a red ball escapes, the level is over. Turn just as it reaches the exit and it bounces back inside: +25, once per level.

Balls that leave one after another in the same turn are worth more and more. Most targets need at least one good chain.

240 levels

Twelve chapters on one turning wheel.

Each chapter brings a new mechanic, mixes it with the ones you already know, and ends with a boss. Turn the wheel on the home screen to go back to any chapter you have reached.

Duo Mode: a blue box and a red box side by side with a two-minute clock between them

Duo Mode

Two boxes. One phone.

Turn the phone sideways and a second arena appears next to the first.

  • Solo: one tap turns both boxes. Keep two different puzzles alive with a single decision.
  • Versus: lay the phone flat between you. Every ball you drop lands in your friend’s box.
  • Two minutes, highest score wins, and both players can tap at the same instant.

Level 120, the Customs boss: colour gates, a one-way flap and a bumper in one box

Bosses

Every chapter ends with a boss.

The twentieth level of each chapter puts everything you have learned into one machine.

  • Gates, flaps, springs and vents working against you at once.
  • Clear it and the wheel turns to the next chapter.
  • Real physics: the same level never plays out exactly the same way twice.
