Size It Up Unlimited

How Size It Up Unlimited works

Start another five-round game whenever you like. There is no daily attempt limit, timer or sign-up. Each game gives you a known reference and a purple silhouette to resize, with up to 100 points per round for an accurate estimate.

Unlimited play, a finite library

New games draw from the existing comparison library rather than inventing new measurements. Objects and pairs can reappear; the game avoids recently played pairs where possible. Finishing a game lets you start a fresh set without waiting for tomorrow.

Turn each reveal into a reference point

Check whether you were estimating height, length or diameter before comparing your guess with the answer. Animals use the representative example described in their source note, and a vehicle’s length is different from its height. Map areas only compare with other map areas.

Try remembering one familiar reference, then judge the next object as a fraction or multiple of it. Use the slider for your estimate and Fit view when a silhouette leaves the board; changing the view does not change your answer.

Where do practice scores go?

Unlimited games do not change your Daily record. Choose the daily size challenge for the shared puzzle, or the past daily challenges to replay a date. For a fixed set to master, pick a themed comparison collection. For bigger-or-smaller decisions and combo points, try Scale Streak.
