Strange Measures
Read full descriptionHide full description
How many bananas tall is the Eiffel Tower? How many worker ants equal the height of the Sears Tower? Most trivia games test facts you memorized in school. Strange Measures tests your spatial intuition, logic, and order-of-magnitude reasoning through absurd real-world scale comparisons. You do not need to know the exact number. You just need to narrow it down. DISCOVER SURPRISING SCALE - Guess absurd real-world comparisons across height, length, area, volume, and weight. - Type your guess, read the hot/cold meter, and adjust your scale. No penalty timers or multiple-choice shortcuts. - Unlock the true measurement, step-by-step unit math, and fascinating real-world facts. GAME MODES - Expedition: Procedurally generated estimation puzzles to build your spatial reasoning. - Daily Challenge: One fixed puzzle shared by players worldwide every single day. Keep your streak alive! - Field Test: A fast-paced swipe mode. Hold a base reference in your head and judge incoming objects faster as the scale tightens. - Field Journal: Collect specimen cards, earn medals, and track your estimation accuracy over time. BUILT BY A SOLO DEVELOPER I built Strange Measures because I love Fermi problems, spatial puzzles, and making learning feel like an exploration rather than a lecture. No forced video ads interrupting your play. No energy timers. No endless grind. Just pure estimation puzzles and satisfying "aha!" moments. Download Strange Measures today and start testing your intuition!

Trace a path. Hit the target. CalcWheel is a new kind of math puzzle. Each level is a different wheel of numbers and operators, and you calculate by drawing: drag a path through them and the total updates live under your finger. Let go when it lands on a target — easy to pick up, and surprisingly hard to put down. One rule to know: your path counts left to right, like a pocket calculator — so if you drag 2, +, 3, ×, 4 it evaluates as (2 + 3) × 4 = 20. WHAT YOU GET • 300 levels across six packs, from Starter to Impossible • A new daily puzzle every day — gentle on Monday, powers by Sunday • Five targets on every wheel — three to pass, all five for a star • Hints that reveal a solution one step at a time • Streaks, and a calendar of everything you have solved PLAIN AND SIMPLE • Plays fully offline. No account, no ads, no timers, no lives to wait for. • Dark by default, with a light theme if you prefer one • Seven languages • No tracking and no data collection of any kind CalcWheel is free to play. CalcWheel Pro is a one-time purchase — no subscription — that unlocks all 300 levels, the full archive of past dailies, the two bonus targets on every puzzle, and 20 hints.
