Fourfold

Four-in-a-row raised into the third dimension — drop balls into a 4x4x4 cube and win by connecting four along any line, including the space diagonals.

How to play

Players take turns dropping balls into the 16 columns of a 4x4x4 cube; each ball settles on top of whatever is already in that column. A line of four of your colour wins — and lines run in far more directions than on a flat board, across levels and through the cube's long diagonals. The added dimension makes threats easy to miss, so you must watch the whole volume.

• Drop a ball into any of the 16 columns to stack it upward.
• Line up four of your colour in a row, column, level line or 3D diagonal to win.
• Track threats across all three dimensions — many lines are hard to spot.

Game modes

• Vs CPU — play the computer at Easy, Medium or Hard.
• Two player — pass-and-play on one device.

• Phone & tablet: tap a column to drop — fully touch playable.

Tips & strategy

• The diagonals through the cube are the easiest wins to overlook — check them every turn.
• Central columns touch the most lines, so contesting the middle pays off.
• Set up double threats on different planes; your opponent can only block one.
