Mines on BC.Game, with one catch to check first.
BC.Game isn't a single-game casino — it's a marketplace that mixes its own "BC Originals" titles with games licensed from outside studios. Before trusting any Mines number against this site's Mines calculator, it's worth confirming which Mines you're actually looking at.
One name, more than one implementation.
BC.Game runs its own in-house "BC Originals" Mines — the 5×5, 1-to-24-mine version this page and the calculator model. But BC.Game's library also carries Mines-style titles from other studios, and those can run different grids, different mine ranges, or a different RTP entirely under the same "Mines" label.
Open the game's info panel (usually an "i" icon in the game window) and check the stated RTP and provider name. If it says "BC Originals" and a 5×5 grid, you're on the version this guide covers and every number here applies directly. If it names a different studio, treat this page as a general reference for how Mines-style math works, not a literal match — go check that title's own published RTP instead of assuming it's the same.
Same hashing approach as the rest of the industry.
Seed pair, not a black box
BC Originals games use a server seed (BC.Game's side) and a client seed (yours, editable) run through a cryptographic hash to generate outcomes — the same seed-pair model used across nearly every provably fair crypto casino game.
Committed before you bet
The server seed is hashed and shown to you before the round starts, so it can't be swapped after your bet lands. Every step of the generate-and-reveal process can be independently checked.
Verify it yourself
Rotating your seed pair reveals the previous server seed, which you (or a third-party seed checker) can re-hash against your bet history to confirm the mine layout matched what the game actually dealt you.
Public figures for BC Originals' Mines RTP range from about 98% to 99% depending on the source — the calculator on this site uses the 1%-edge (99% RTP) convention shared with Stake and most other Mines implementations, so treat any number here as an estimate rather than BC.Game's exact internal constant. If you're chasing a precise figure, the in-game info panel is the authoritative source, not a third-party guide.
Questions specific to BC.Game's setup.
Does every Mines game on BC.Game use the same RTP?
No. BC.Game hosts its own BC Originals Mines alongside Mines-style games from other studios, and each provider sets its own RTP and rules. The ~98–99% figure and the numbers on this site describe BC Originals specifically — check a given game's info panel before assuming it matches.
Is BC Originals Mines the same math as Stake's?
Structurally yes — 5×5 grid, 1–24 mines, same combinatorics — but the exact RTP constant differs slightly by source (roughly 98–99% cited for BC.Game versus the 99% convention used for Stake). Close, not necessarily identical.
How are BC Originals Mines multipliers calculated?
The mechanics are the standard Mines formula, just tuned to whichever RTP constant BC.Game runs internally.
The formula
- Win chance for m mines and k safe reveals is C(25−m, k) ÷ C(25, k) — the odds all k picks avoid every mine.
- Fair multiplier is 1 ÷ win chance — what the payout would be with zero house edge.
- Actual multiplier is the fair multiplier × the RTP constant — 0.99 on this site's calculator, matching the widely-cited convention.
Worked example — 3 mines, 3 tiles revealed
- Ways to pick 3 safe of 22: C(22,3) = 1,540
- Ways to pick 3 of all 25: C(25,3) = 2,300
- Win chance: 1,540 ÷ 2,300 = 66.96%
- Fair multiplier: 1 ÷ 0.6696 = 1.49×
- At the 99% convention: 1.49× × 0.99 = 1.48×
What's the minimum bet for BC Originals Mines?
Commonly cited as low as $0.0001 (or the crypto equivalent), among the lowest minimums of the major crypto casinos — useful if you want to test a mine count with minimal exposure before betting seriously.
What's the maximum win on BC Originals Mines?
Third-party sources commonly cite a $1,000,000 max win with a maximum multiplier around 3,333× on the standard configuration — figures from outside review sites rather than BC.Game's own published documentation, so treat them as approximate.
How do I check BC.Game's Mines is fair for my own bets?
Use the provably fair panel in your account to rotate your seed pair and reveal the prior server seed, then re-run the hash against your bet history — either by hand or with a seed-checking tool — to confirm the mine layout matched what was dealt.
Is there a best mine count to use on BC.Game?
No — mine count changes variance, not the underlying edge, on any implementation of this game. Low counts mean frequent small wins; high counts mean long droughts and rare, huge multipliers. The full trade-off is broken down on the mine-count strategy guide.
