Game Mechanics and Scoring
The official website of k30. Ceiling Cube Gap Reels uses two independent uniform reels showing hexadecimal symbols 0..9 and A..F (values 10..15). Each reel value is an integer from 0 to 15. The integer n is calculated as n = 16*first + second + 1, resulting in an integer uniformly distributed from 1 to 256.
The statistic is the difference between the smallest perfect cube greater than or equal to n and n. The reward score is calculated by subtracting the exact minimum statistic over all 256 outcomes from this value. The exact subtracted minimum is 0.
The score function is defined as:
- score(n) = statistic(n) - 0
Before capturing the stake, you select linear, squared, or cubed weights of that score. The gross multiplier is 0.96 * weight divided by its exact 256-outcome mean.
Payouts and Settlement
Each round involves one captured stake. At settlement, the floor of (raw gross return + stored fractional carry) is credited to the balance. The remainder persists as fractional carry. Zero-return rounds leave the fractional carry unchanged.
There is no intermediate collection. The entire reels share one stake, with no row bets, bonus features, or interim collections.
Controls and Modes
Selectable stakes are 10, 20, 50, or 100 play coins, with a default of 20. You can choose linear, squared, or cubed reward weight before the captured stake. Settings, restoration, and starting another round are locked while a round is active.
Wallet and Persistence
The initial balance is 1000 virtual coins. A manual idle-only restoration sets the balance to exactly 1000 when eligible (idle, balance below 10). This is not automatic replenishment or adding coins.
Fractional carry persists in browser localStorage across settlement, refill, and reload. Refilling does not clear it. Settled balance persists locally, including zero.
If you reload during an unfinished round, the captured stake remains deducted. The unfinished round ends without refund, payout, continuation, or resume. Controls after reload reset to default stake (20) and first preset.
Mathematical Evidence
The following table shows the exact expected RTP and measured estimates from simulation data. Expected RTP is not a promised session result.
| Mode | Expected RTP | Measured RTP | Exact Gross RTP |
|---|---|---|---|
| 0 (Linear) | 96 | 95.95 | 24/25 |
| 1 (Squared) | 96 | 96.02 | 24/25 |
| 2 (Cubed) | 96 | 96.12 | 24/25 |
Privacy and Storage
Virtual-coin balance and fractional payout carry are stored in browser localStorage. Clearing cached files may leave local storage intact if not explicitly cleared. The page template loads Google Fonts stylesheets and font files.

Frequently asked questions
Is Ceiling Cube Gap Reels an official game from a specific operator?
No. This guide is independent. The query name does not establish an official company, account address, app, or service. The demo belongs to this guide and does not certify or reproduce any outside product.
How does the wallet restoration work?
Restoration is manual and idle-only. It sets the balance to exactly 1000 when the balance is below 10 and the game is idle. It is not automatic replenishment. Fractional carry persists across reloads and refills.
What happens if I reload during a round?
The captured stake remains deducted. The unfinished round ends without refund, payout, continuation, or resume. Controls reset to default stake (20) and first preset.
