Antimatter Dimensions is an incremental game by the Finnish developer Hevipelle. It began as a solo project in 2016 and grew a large team¹. It runs on the web, Google Play, the App Store, and Steam². The full source is public under the MIT license, and the in-game credits list 207 people (bibliography).

#Prices

The eight tiers of dimensions cost antimatter³. Prices scale exponentially in steps: each tier’s price stays flat for 10 purchases, then jumps by its multiplier⁴. Tickspeed upgrades use the same scheme at ×10 per purchase, not per set⁵.

Every price comes from one class, ExponentialCostScaling⁶. Once a price passes Number.MAX_VALUE ≈ 1.8 × 10³⁰⁸⁷, each set’s multiplier grows by another factor of 10⁸, so log price grows quadratically. A Break Infinity upgrade can cut that factor to 3⁹. The same amount of antimatter unlocks Infinity, the first prestige reset¹⁰.

Tier	First price¹¹	× per 10¹²	Sets before the extra scaling⁷
1	10	10³	103
2	100	10⁴	77
3	10⁴	10⁵	61
4	10⁶	10⁶	51
5	10⁹	10⁸	38
6	10¹³	10¹⁰	30
7	10¹⁸	10¹²	25
8	10²⁴	10¹⁵	19

“Buy until 10” is exact, because the price is flat within a set¹³. Max-buy charges only the most expensive set it buys, about 0.1% under the true sum¹⁴ at ×1,000 per set. A code comment says so¹⁴.

Every claim about this game, by concept (14)

general	Dimensions cost antimatter, except in Normal Challenge 6, where tiers 3 and up cost the dimension two tiers below.	T3
	The About screen says Finnish developer Hevipelle began the game as a solo project in 2016, later expanded by a large team.	T2
	The About screen links versions on Google Play, the App Store, and Steam, alongside the web game.	T2
Bulk buying	“Buy until 10” charges price × purchases left in the set (`costUntil10`), exact since the price is flat within a set.	T3
Bulk buying	Max-buy (`getMaxBought`) counts the whole sets affordable but charges only the most expensive set × 10, about 0.1% under the sum at ×1,000 per set.	T4
Exponential cost scaling	The eight Antimatter Dimensions start at 10, 100, 10⁴, 10⁶, 10⁹, 10¹³, 10¹⁸, and 10²⁴ antimatter.	T4
	After every 10 bought, tiers 1–8 multiply their price by 10³, 10⁴, 10⁵, 10⁶, 10⁸, 10¹⁰, 10¹², and 10¹⁵, about 2.0× to 32× per purchase.	T4
	A dimension's price is $calculateCost (⌊ bought / 10 ⌋ + costBumps)$ : flat for each set of 10, then a jump; `costBumps` moves only in Normal Challenge 9 and Infinity Challenge 5.	T4
	`ExponentialCostScaling.calculateCost(n)` returns $B \cdot C^{n}$ , times $S^{e (e + 1) / 2}$ once $n$ exceeds `purchasesBeforeScaling` by $e$ , so the ratio between steps grows by $S$ each step.	T4
	The threshold, `Number.MAX_VALUE` (≈ 1.8 × 10³⁰⁸), becomes $⌈ (\log threshold - \log B) / \log C ⌉$ sets: 103 (1,030 bought) for the 1st Dimension, and 19 for the 8th.	T4
	The post-threshold factor $S$ , `Player.dimensionMultDecrease`, is 10 minus the effects of the Break Infinity upgrade `dimCostMult` and Eternity Challenge 6's reward.	T4
	The `dimCostMult` upgrade (“Reduce post-infinity Antimatter Dimension cost multiplier scaling”) lowers $S$ by 1 per purchase, at most 7 times, to 3 before Eternity Challenge 6; it costs $10^{7} \times {5,000}^{purchases}$ Infinity Points.	T4
	Tickspeed upgrades use the same class per purchase, not per 10: with $n$ bought, the next costs $1,000 \times 10^{n}$ antimatter up to the `Number.MAX_VALUE` threshold (306 purchases), and past it their own factor, `Player.tickSpeedMultDecrease` (10 without upgrades), applies.	T4
Prestige	Outside challenges, a Big Crunch (Infinity, the first prestige reset) unlocks when this Infinity's peak antimatter reaches `Decimal.NUMBER_MAX_VALUE`, the cost threshold's ≈ 1.8 × 10³⁰⁸.	T3
