How a round of Sweet Mania unfolds
One question at a time, one honest commitment, one clear answer. Here is what you do before and after you lock in a guess.
Before you answer
- Read a real-world quantity question, for example how many days an adult mayfly usually lives.
- Pick a topic: Distance & Size, People & Places, Time & History or Money & Scale. You can also build your own set.
- Set the difficulty band to Easy, Mixed or Hard. The Mixed band lists 120 matching items.
- State how sure you are. That confidence is what the app tests next.
After you answer
- A slider places a Truth marker beside your own marker so the distance is obvious.
- A plain verdict such as Too high appears with your points, even when that is 0 points.
- The true value and a Worth remembering note explain what to keep.
- Tap Why this score for the reasoning, Next item to continue, or Break this one down to chain smaller estimates.
Six tools that make estimation stick
Everything below appears in the app itself, from the calibration charts to the slot-style celebration screens.
Calibration dashboard
Stated confidence is set against your real hit rate. The top bar shows what you claimed, the bottom bar what you achieved, with a gap value for each level.
Break it down
Chain estimates into one answer. Cards such as Households with a piano and Tunings per tuner per year let you multiply or divide, then switch the operation in a tap.
Four topic sets
Distance & Size covers how far, how tall and how wide. People & Places handles crowds, cities and countries. Time & History spans years, days and seconds. Money & Scale deals in prices, budgets and economies.
Easy, Mixed and Hard
A three-way band selector narrows the question pool to your comfort level, and a counter tells you how many items match before you begin.
Width efficiency and points
See how much of 100 your brackets earn when they hold, plus your average points across all answers. Recent sets plot the trend as a line.
Slot-style celebrations
Strong rounds trigger SUPER and WIN! screens with multiplier badges like x10, x95 and x719, set among grapes, bananas, hearts and candy canes.
How Sweet Mania measures your judgement
Sweet Mania runs on a simple loop. A question asks for a real-world quantity, you place an estimate on a slider, and you state how confident you are. The app then reveals a Truth marker next to yours, so the gap between belief and fact is something you can see rather than guess at.
Scoring is not only about closeness. Points reward estimates whose range holds the real value, and the width efficiency figure, shown out of 100 on brackets that hold, tells you how tight those ranges were. A wide bracket is safe but earns little. A narrow one pays only when it lands.
Behind the sweets sits a plain study layer. The Calibration tab compares each confidence level with your actual hit rate and prints a gap, such as gap +13 at 80 percent. Across several sets, the Recent sets line shows whether your judgement is settling, and the Break it down tool shows which factor carries the most weight in a chained answer.
