02The game
How it plays, and where it fits.
The game
- What the player does
- The player picks a wall of 25, 36 or 49 safety-deposit boxes and how many hold a dye pack, then opens boxes one at a time; every gem raises the multiplier until they cash out or open a dye pack.
- Why players come back
- Mines in a vault of deposit boxes, in real-time 3D: the gem in each box grows with the multiplier, a gem and a dye pack take exactly as long to show, and every wall is dealt from seeds the player can check.
- Round structure
- Multi-step cash-out ladder. One stake, open boxes one at a time, cash out after any gem.
- Session fit
- Quick or long sessions: a round is seconds to a minute. Single player. Good to watch: built for streams.
- Stakes in this build
- 0.10 to 100 demo credits. 0.10 to 100.00 per round.

03The maths
Every number, from the code.
| Mode | RTP | House edge | Hit rate | Net win | Volatility (SD) | Max win | GGR / 1,000 rounds |
|---|---|---|---|---|---|---|---|
| 5x5, 3 dye packs: cash out after 3 gems (default wall and packs) headline | 97.76% | 2.24% | 66.96% | 66.96% | Low (0.69) | 1.46× | 22.43 |
| 5x5, 1 dye pack: cash out after 5 gems | 97.60% | 2.40% | 80.00% | 80.00% | Low (0.49) | 1.22× | 24.00 |
| 5x5, 10 dye packs: cash out after 3 gems | 97.92% | 2.08% | 19.78% | 19.78% | Medium (1.97) | 4.95× | 20.76 |
| 6x6, 8 dye packs: cash out after 5 gems | 97.76% | 2.24% | 26.07% | 26.07% | Medium (1.65) | 3.75× | 22.39 |
| 7x7, 5 dye packs: cash out after 5 gems | 97.96% | 2.04% | 56.95% | 56.95% | Low (0.85) | 1.72× | 20.43 |
| 7x7, 48 dye packs: one box | 98.00% | 2.00% | 2.04% | 2.04% | High (6.79) | 48.02× | 20.00 |
Walls
| Wall | Dye packs | Cash-out points | RTP at every point | Top payout |
|---|---|---|---|---|
| 5x5 25 boxes | 1 to 24 | 256 | 97.28% to 98.00% | 9,100.52× 9 packs |
| 6x6 36 boxes | 2 to 35 | 428 | 97.17% to 98.00% | 9,875.16× 8 packs |
| 7x7 49 boxes | 2 to 48 | 692 | 97.22% to 98.00% | 9,954.18× 15 packs |
The 5x5 wall is Mines Classic’s maths exactly. On every wall each multiplier is 0.98 divided by the chance of opening that many gems in a row, rounded down to the hundredth, so each of the 1,376 reachable cash-out points returns between 97.1666% (6x6, 3 dye packs, cash out after one gem) and 98.0000%. Any way of playing is a mix of these points, so it returns between the two. No round pays 10,000× or more: where the multiplier would reach that limit, the round banks itself on the last gem before it. The 6x6 and 7x7 walls start at 2 dye packs so the first gem always pays more than the stake. Each wall is dealt in full before the first box opens, from HMAC-SHA256 of the server seed (the Baize RGS scheme); opening a box draws nothing, and Pick for me takes the next number in the same stream.
Pace
1.0 s a round, about 3,529 rounds an hour. Measured in Chrome with every control pressed as soon as it was enabled, so this is a ceiling with no thinking time.
GGR / 1,000 rounds is the theoretical gross gaming revenue from 1,000 rounds at a total stake of 1.00: house edge × 1,000. Volatility is the standard deviation of one round’s total return per 1.00 of total stake. Low under 1.5, Medium 1.5 to under 5, High 5 to under 15, Very high 15 and over. For scale: an even-money roulette bet is 1.00, a straight-up number 5.84.

Demo-credit build, not certified. Walls are dealt in the player’s browser today from a provably fair seed pair, the Baize RGS scheme; real-money play moves the seeds to the RGS. See status for what real-money use needs.
