The Rings

The Rings strips the genre back to almost nothing: coloured rings, a board, and one rule — arrange rings of the same colour into a straight line and they are destroyed. The game ends when there is no space left to place another.

That ending condition is what makes it hard. Every ring you place is a commitment, and space is the only resource; a board played greedily fills from the edges inwards and locks. Good play looks conservative — keeping the middle open, finishing lines rather than starting three at once — and it is genuinely difficult to sustain once the board gets busy.

The minimalist look is not decoration but function: with nothing else on screen, the only thing to read is the shape of the space you have left.

1. Look at the board before placing — space is the resource.
2. Place a ring where it extends a line of its own colour.
3. Complete straight lines to destroy the rings and free room.
4. Keep the centre open; the run ends when nothing fits.

Finish lines you have already started before opening a new one. Two half-built lines occupy twice the space of one complete clear, and space is the only thing standing between you and the end of the run.
