Each square is one fold, colored by the pairs it merged: 🟨 1 · 🟦 2 · 🟥 3 or more. Failed tries stay ⬜.

Ranked by fewest tries, then fewest folds, then fastest solve.
Days in a row with the daily strip solved.
Weekly points: 5 for solving, 3 more for a first-try solve, 2 more for matching par. The week starts Monday.
Fold the strip down to one cell.
Tap a crease and the shorter side folds over onto the longer one. Every cell that lands on another must match it, and matching cells merge into their sum. On a touchscreen, the first tap aims and lifts the side that will fold; tap the same crease again to fold.

Folding near the middle merges many pairs at once, but only when both sides mirror perfectly. Most folds lead to dead ends, so read the symmetry before you crease. Par is the fewest folds that solve the strip.
Monday's strip is the gentlest. Each day gets harder, up to Sunday's 12-cell Big Fold.
