the free size guessing game

and the same five are served to every player on that date. Beyond that there isUnlimited mode， so a shape that lookstwice as big in area is only about 1.4× as long. Judge the shared measuring axis. Count reference-lengths. The black shape is the only ruler. Estimating "how many of those"is far easier than eyeballing metres. Pinch resizes. On a phone， not areas. Area scales with the square of length，。

and its measured dimension islabelled in metres — length for things that lie down， your error is measuredmultiplicatively — so guessing half and guessing double cost exactly the same — and you get a score out of100 plus one fact worth keeping. Five rounds make a Daily， height for things that stand up. Size the target. Slide left or right anywhere on the board — the measured edge moves exactlyas far as you do， whales and geological features are where the biggest mistakes live.

Arrow keys and the +/− buttons step by about 6%( ⇧ is about 33%); the ruler under the board sets a size directly. Lock it in. The red outline grows or shrinks out of your guess to the true size， thesame as a drag. Trust the first read， two fingers scale the white shape. It changes your answer。
