Every pack evaluation starts from one frame: convert the contents to gem-equivalents, then compare against the gems-per-dollar baseline of plain gem purchases. A pack is only "a deal" relative to what raw money buys.
Why gem-equivalents and not gut feel: the game itself prices this way. Some reward chests display a "Reward Value" field quoting the contents in gems — direct in-game corroboration that gem-equivalence is the native accounting unit, not an analyst's invention.
The method:
- Itemize. List every item and quantity. A pack you can't itemize is a pack you can't price — headline banners ("worth 8,400 gems!") are marketing claims to be checked, not accepted.
- Convert each item to its gem value using in-game purchase prices where they exist (speedups, resource packs, and most utility items have gem-shop analogues).
- Divide total gem value by price, and compare to the plain gem-purchase baseline. A pack beating baseline by 6–20× is routine; the best recurring packs run far higher — which is exactly why the baseline matters as the yardstick.
Traps this method catches:
- Banner inflation. The "worth X gems" headline typically values items at full shop price, including items you'd never buy at shop price.
- Items with no honest gem price. Legendary sculptures and rare materials have no stable shop analogue; when a pack's value rests mostly on those, the gem frame says insufficient data, not a big number. An honest evaluation names which slice of the value is unpriceable.
- Denomination illusions. Ten small chests read richer than one large one. Convert first, count later.
Whale application: the frame ranks packs against packs too — the same dollars land wildly different gem-equivalents across a store page, and the ordering is rarely the visual one.
