# Thousandfold > A playful thought experiment for one ordinary thing a person does or keeps - a Friday pizza night, a jar > of spare buttons, an open window in the morning. Give what it is, what it is for, the amount, how many > people take part and how long one go takes. A free in-browser engine works out five extremes - a > thousand times the amount, a thousandth of it, a thousand times the people (each with the usual share), > one go a thousand times faster and a thousand times slower - and draws them as a shelf of six nesting > dolls. A metered stress test judges each extreme against what the thing is for: snaps, bends or holds, > what gives way, what survives and what it shows about the normal-sized version. Derived from > @obra/scale-game. https://thousandfold.skillsafe.ai/ ## What it does - The figures: the page writes every extreme's figure itself (for example 2 pizzas -> 2,000 pizzas, 90 minutes -> about 63 days), so the read never has to do arithmetic. - The strains, checked in a fixed order against what the thing is for: snaps (it can no longer do that at all), bends (it still can, only rearranged), holds (it still can the same basic way). - The verdict follows from the count of snaps: none is sturdy, one or two is cracks, three or more is made-to-measure. - Free downloads: the doll shelf (SVG, PNG), the five extremes (CSV), and the whole thing with the read (Markdown, JSON). - Saved things (opt-in) keep the form and the latest read, and show how the snaps moved between runs. ## The paid task One task, `scale`, on gpt-terra, metered per run. The input is six string fields: `task`, `thing`, `purpose`, `note`, `normal` (the figures as they are now) and `extremes` (five lines: id, what changes, now -> pushed to). The reply is one JSON object: headline, verdict (sturdy | cracks | made-to-measure), extremes[] of {id (bigger | smaller | crowd | instant | forever), strain (snaps | bends | holds), breaks, survives, shows}, core_truth and keep. The page re-checks the reply: all five extremes present, the verdict matches the count of snaps, the headline's count matches, and no number appears that the page did not write. A thought experiment, not professional advice: nothing in it suggests trying an extreme for real. - API tutorial: https://thousandfold.skillsafe.ai/api.html - Source skill: https://skillsafe.ai/skill/@obra/scale-game (obra/superpowers-skills, MIT)
