SumLoop

Rotate the ring. Match the target. Keep the loop clear.

Sumloop is a simple number puzzle where you rotate a circular ring and find two neighbouring numbers whose sum matches the target.

Every successful match clears tiles, but new numbers continue entering the ring. Plan your moves carefully and avoid letting the ring fill completely.
