THE UNLIMITED MODE GUIDE
An open practice room for real-world scale.
Play at your own pace · your Daily streak stays separate
Why play Size It Up Unlimited?
The Daily Size It Up puzzle is deliberately short. Five shared rounds give everyone the same small challenge, and the wait until the next set is part of what makes a streak feel meaningful. That format is great for a daily habit, but it is not enough time to build a reliable sense of scale. Unlimited is the practice room: a place to play another round immediately, test a hunch, and turn a surprising answer into a useful mental reference.
After several rounds, familiar anchors start to travel with you. A bus, a person, a tennis court, a landmark, or a blue whale stops being only an image and becomes a rough measurement you can carry into the next comparison. Size It Up Unlimited is for players who finish the Daily game in a few minutes and want more, as well as anyone who wants to learn through repetition instead of memorising a list of numbers. There is no pressure to protect a streak here. Keep playing while the questions are interesting, then come back to the Daily challenge when you are ready.
How the unlimited size guessing game works
Every round asks you to compare two real-world objects on the same visual stage. The blue cut-out is the known reference and gives you an anchor. The violet cut-out is the target: drag it, use the ruler, or make a smaller adjustment with the controls until its size looks right beside the reference. You do not need to know the answer before you begin. The challenge is to make a reasonable visual estimate from the relationship between the two shapes.
When you lock in, Size It Up reveals the target’s actual red outline, its real measurement, your estimate, and the score for that round. The pair is chosen from the playable Size It Up library, so an Unlimited run can move between animals, geography, vehicles, dinosaurs, space, landmarks, insects, and everyday objects. Mixed rounds keep the practice surprising; the category selector lets you stay with one kind of comparison when you want a more focused session.
1 · Compare
Start with the fixed blue reference and use its visible shape as your scale anchor.
2 · Resize
Adjust the violet target until the proportions feel convincing, then take one last look before submitting.
3 · Reveal
Lock in your estimate to see the actual outline, measurement, error, and score.
Practice the hard comparisons
Some objects are difficult because photographs hide their dimensions. You may recognise a giraffe, a bridge, a planet, or an aircraft immediately and still have no good instinct for its length or height. That is exactly where an open-ended size comparison game helps. A familiar reference turns an abstract number into a relationship you can see, and the field note beneath each round gives you one more detail to remember after the reveal.
Try moving between very different categories. Everyday objects help you build a local baseline; vehicles and landmarks stretch that baseline; animals and dinosaurs make you judge body length instead of overall visual drama; space comparisons test how quickly your intuition breaks when the units become enormous. Unlimited gives you enough repetitions to make those mistakes useful. A wrong estimate is not a dead end when the answer shows you what the scale should have looked like.
How scoring works in Unlimited mode
Unlimited uses the same ratio-based scoring curve as the Daily puzzle. A guess within six percent of the true size earns 100 points. A guess that is about half or double the correct size earns roughly 45 points, while an estimate five times away scores zero. The important part is that the comparison is multiplicative: guessing twice as large and guessing half as large are treated symmetrically.
That scoring model rewards better visual anchors rather than a habit of always guessing small. You can use the score as feedback, but the reveal is the more valuable part of a practice run. Notice which references helped, which silhouettes fooled you, and whether the error came from choosing the wrong unit, the wrong orientation, or the wrong order of magnitude.
Tips for making better size estimates
A good estimate usually starts with a comparison you already understand. Before touching the target, decide whether it should be smaller, similar, or larger than the reference. Then refine the ratio. The goal is not to guess a hidden number from memory; it is to build a visual argument and see how close it gets.
Use the reference first
Look at the known object before focusing on the target. Its length or height is the stable part of the round.
Think in multiples
Ask whether the target is half, equal to, twice, or several times the reference before fine-tuning.
Separate height from length
A tall object and a long object can occupy a similar visual area, so check which dimension the silhouette measures.
Use the ruler for the last step
Drag for the broad adjustment, then use the slider or smaller/larger buttons when the estimate is nearly right.
Treat every reveal as an anchor
Remember the relationship between the pair, not just the final number. The next round may give that memory a new use.
Play Size It Up Unlimited in your browser
Size It Up Unlimited runs directly on this page. On a desktop, use your pointer to drag the violet silhouette and the mouse wheel or ruler controls to fine-tune it. On a touch device, drag the target and use the on-screen smaller and larger buttons when you need a precise adjustment. The game is designed to keep the interactive board near the top, with the explanation below it for players who want to understand the rules before another run.
Your current Unlimited round is kept in this browser so you can return without losing your place.

Questions about Size It Up Unlimited
What is Size It Up Unlimited?
It is the open-ended mode of the Size It Up size comparison game. You compare real-world silhouettes, resize the target beside a known reference, reveal the answer, and continue to another round without the Daily game’s five-round limit.
Does Unlimited affect my Daily streak?
No. Unlimited practice is stored separately. Only completed Daily rounds contribute to the Daily streak, so you can experiment here without changing your Daily result.
How is Unlimited different from the Daily game?
The Daily game gives everyone the same five-round set for the day. Unlimited keeps the same scale-comparison idea and scoring style but lets you continue with additional selections from the playable library.
What categories can I play in Unlimited mode?
The library includes Mixed, Animals, Geography, Vehicles, Dinosaurs, Space, Everyday Objects, Insects, and Landmarks. Use the category selector in the game to focus your next session.
Can I play Size It Up Unlimited on a phone?
The board supports touch pointer input and on-screen smaller and larger controls. Desktop pointer and ruler controls give you the most room for fine adjustments, while a phone is useful for a quick practice round.
How does Unlimited scoring work?
Scoring compares your estimate with the true size as a ratio. Within six percent earns 100 points, an estimate around half or double earns about 45 points, and an estimate at least five times away earns zero.
Where is my Unlimited progress saved?
The current round and estimate are saved in your browser’s local storage. Clearing site data or switching browsers can remove or reset that local progress; account syncing can be added later as the site’s login features develop.
