Rotation · sorting

Torque

Rotate 2×2 quadrants to sort the grid. Par 8, every day. Deceptively gentle; genuinely maddening at move six.

Words · chains

Linchpin

Six words; every neighboring pair joins into a compound or common phrase (SNOWBALL, PARK BENCH). The first and last are free — the middle four are yours to find.

Spatial · tiling

Inlay

Eight-ish pieces, one board, zero gaps. Every daily board is carved from a real partition, so the fit always exists.

Numbers · deduction

Switcheroo

Someone swapped three pairs in a finished grid. The row and column sums remember. Put everything back in three moves.

Logic · measuring

Pour Over

Three vessels, one full. Measure exactly the target — nothing more, nothing less — in as few pours as the math allows.

Light · placement

Glint

One beam, a handful of mirrors, every gem. Bend the light until the whole board glitters.

Memory · recall

Afterimage

The pattern shows once, then it's gone. Rebuild it from memory through ten escalating rounds — one slip ends the run.
