Pillars

About the game

Columns of three jewels fall into a narrow well, one after another. You move a column left and right, and you can cycle the order of its three jewels. When it lands, any line of three or more jewels of the same kind, whether across, up and down or diagonal, disappears, and whatever sits above it falls down and may form new lines.

Those chain reactions are where the big scores come from. The well keeps filling up, the columns fall faster as your level rises, and the game ends when the stack reaches the top. A preview shows the next column, and a ghost column shows where yours will land.

Playing it here

Click Play. Move with Left and Right, press Up until the colours are in the order you want, then press Down or Space.

A few things worth knowing

Use the diagonals. Most players only watch rows and columns, so diagonals are free combos.

Keep the middle low. A tall stack in the centre leaves less room to steer.

Plan for chains. Clear from the bottom so the pieces above fall into new lines.
