How it plays

Look down the well

You see a 7 × 7 well from above, twelve layers deep. The colour of each cube tells you how deep it sits.

Turn it three ways

Spin, roll and tip each piece, move it over the well and drop it. A full layer clears and everything above sinks.

Two ways to play

Classic, until the well fills to the top. Or Timed: three minutes to place as many cubes as you can.

Made for everyone

Touch, keyboard, mouse or gamepad. Colour-blind and high-contrast palettes. It keeps playing with no connection.
