COLD SUM
COLD SUM is a standalone, no-build number-pair puzzle rendered as a kinetic glass instrument. Pair equal counters or counters totaling ten along a clear horizontal, vertical, diagonal, adjacent, or wrapped row-edge path. Empty rows retract; when no legal path remains, feed every survivor back into the instrument.
