CUTLY: Cut in Half

A geometry puzzle about judging area by eye. One shape, one straight line: where do you cut so both parts come out equal? The halves drift apart, each showing its share of the area; an error of 1% or less earns three stars, 3% two, 5% one.

Classic mode holds 32 levels in five stages, Basics to Special. No clock, unlimited attempts, one star unlocks the next. No shape here is symmetrical, so a line down the middle will not save you.

Figure of the week keeps one of silhouettes up for seven days. Attempts are unlimited and only your best run counts: accuracy to thousandths of a percent, time to the millisecond. Finished weeks stay in an archive.

Figure of the day brings a new shape daily and one attempt at it: the cut counts at once. Its catalogue of hundreds silhouettes is picked so that an eyeballed line through the middle misses by at least 10%.

The weekly and daily modes each keep a top 10, open to signed-in players only.
