Mines Grand by JILI
Mines Grand adds a Treasure Pot to the coin-and-bomb format. JILI lists it as product 546, making it a separate game from Mines and Mines Gold. Official Mines Grand page.

Demo game
Use the JILI player below to try Mines Grand with practice credits. It is the exact title’s launch address, not a substitute from another studio. The game loads only after Play; the new-tab link provides an alternative when embedding is restricted.
Use a practice session to locate Help, the stake control and the way a round ends. Keep the displayed virtual balance separate from any casino wallet. Closing this page or restarting a demo is not a cash-out action.
The provider publishes this exact game demo address. Loading remains subject to its current browser and regional restrictions. If it cannot load here, use the new-tab link. Read the game source.
How to play
- Identify the edition. Check Mines Grand and JILI in the player or information panel.
- Read the setup. Confirm product 546 and read the Treasure Pot rules before a practice stake. Track the main round’s amount separately from the pot indicator.
- Inspect the stake and return. Note when a stake is committed, whether a displayed multiplier includes that stake, and which control ends the round.
- Follow this game’s progression. A pot can have contribution, eligibility and reset conditions. Do not add its headline amount to an ordinary cash out.
- Check the completed result. Compare the settled amount with the round history where available. Stop to read Help if a feature changes the normal sequence.
Controls and feature limits
The Treasure Pot is a distinguishing feature of Mines Grand. Read its contribution, eligibility and reset rules in the active player; the presence of a pot meter alone does not establish whether it is shared or personal. A visible pot value is not a guaranteed award.
The Treasure Pot distinction
The provider describes accumulating a pot connected with a jackpot feature. That description identifies the feature, but it does not establish all of its payment conditions.
A pot display should not automatically be read as money already available to collect. A complete rule explanation must distinguish the current round’s return from any jackpot amount, then explain how the player qualifies for each.
Questions a jackpot rule must answer
The decisive details are the trigger, any contribution from the stake, eligibility at different bet levels and what happens when the pot resets. It also matters whether the pot belongs to one player, one game session or a wider pool. The short product description does not settle those questions.
Until those rules are available, a numerical example combining a normal cash out and the pot would be speculation.
Comparing Grand with Gold
Mines Gold’s gold-related bonus is not evidence for Mines Grand’s Treasure Pot. Use the Grand title and its own information panel when identifying the game. A shared Mines theme cannot establish matching mine counts, payout tables or theoretical return.
The exact provider demo is linked above. Canadian operator eligibility and the Treasure Pot settlement conditions remain separate checks.
Probabilities and calculator
The calculator starts with an illustrative 5 × 5 board and 5 mines. With uniformly random fixed mines, the first safe pick has probability 80%. Subsequent picks use the remaining cells: after one safe reveal, both the number of safe cells and the number of unopened cells fall by one. This example does not establish an available game setting.
The table reports the chance that all selected cells are safe, measured from the start. It is not the conditional probability of the next pick after earlier successes. Neither value is a payout multiplier. The tool excludes special symbols, feature awards, stake changes and operator caps; use the probability guide for the underlying distinction.
Explore the fixed-board model
Mines are assumed to occupy uniformly random fixed positions. Each new pick opens a different cell, without replacement. These assumptions explain the calculation; they do not certify the game’s RNG or include bonus features.
Example: 25 cells and 5 mines.
| Picks | All safe under this model |
|---|---|
| 1 | 80% |
| 2 | 63.33% |
| 3 | 49.57% |
| 4 | 38.3% |
Patterns and predictors
The nine examples below show possible arrangements under the illustration’s assumptions. They were generated randomly, independently of casino rounds. They are not the most frequent layouts and do not provide a winning route.
A corner, diagonal or centre-first route does not gain an advantage merely from its shape when hidden positions are uniformly random. A remembered pattern can describe which cells you intend to choose; it cannot reveal the game’s next layout. See predictor claims and the probability tool for the difference between an illustration and a live signal.
Nine generated examples
Each illustration has 5 × 5 cells and 5 example mines. These are random teaching diagrams, not recorded rounds, frequency rankings or live signals. Unmarked cells are safe only in the pictured example.
Where to play and bonus checks
No exact title-and-provider casino match is established by this page’s reviewed catalogue evidence. Start with the official JILI entry and use the casino comparison to compare operator information separately. A lobby listing that says only “Mines” is insufficient.
When comparing an operator, check these points for Mines Grand by JILI:
| Check | Why it matters for this version |
|---|---|
| Exact title and provider | The features listed above belong to this exact title; a similarly named game from another provider may settle differently. |
| Game information | Check the board setup and the active RTP version in the game’s information panel. |
| Eligible-game list | Inclusion in a casino lobby does not establish bonus eligibility. |
| Contribution and restrictions | Verify wagering contribution, maximum promotional bet and any excluded game modes. |
| Currency and settlement | Check the displayed stake currency, maximum award and withdrawal terms separately. |
A casino welcome offer and an in-game feature are different things. In particular, ask: Is the Treasure Pot personal or shared, and what resets it? No universal bonus amount or wagering contribution is established here.
Compare related games
For the related titles discussed in this guide, compare Mines by TaDa / JILI, Mines Gold by TaDa / JILI, Mines Cricket by JILI, Mines Football by TaDa / JILI. Open each title’s own rules before transferring a setting or feature.
| Version | Provider identity | Main distinction |
|---|---|---|
| This game | Mines Grand — JILI | Treasure Pot; product 546 |
| Related version | Mines Gold — TaDa / JILI | Gold bars, dynamite and a gold-related bonus; JILI 254 |
Use this comparison to choose which rules to read, rather than ranking games by a headline multiplier. A higher published RTP alone does not describe session volatility, feature frequency or your chosen cash-out sequence. The Mines game directory keeps the other provider versions separate.
Mobile play and troubleshooting
Try the same official demo address in a current mobile browser. Full screen or landscape can make a dense field easier to use. For Mines Grand, first ensure the field settings and round-ending control remain visible; a small display is not a reason to guess a button’s function.
| Problem | Next step |
|---|---|
| Player is blank | Open the exact demo in a new tab or start again from the provider’s page. Some providers restrict embedding. |
| Demo session has expired | Obtain a fresh session from the official launch entry. Do not treat an old balance as recoverable funds. |
| A region or age screen appears | Follow the provider’s access requirements. This page does not establish eligibility for every location. |
| Settings differ from this guide | Check the title, provider and rules version, then use the values shown in that client. |
| Connection drops during a round | Consult that client’s round history and recovery rules before starting another round. Closing a player does not prove collection. |
Frequently asked questions
Which Mines Grand does this page cover?
This page covers the JILI version of Mines Grand, identified by its exact title. Its distinguishing feature: Treasure Pot; product 546. The comparison below links the related edition rather than treating the names as interchangeable.
Can I play a free Mines Grand demo?
The demo section provides the exact provider launch address. Practice credits cannot be withdrawn. Availability can change, and a blocked embed may still work through the new-tab link.
What RTP should I use for Mines Grand?
A usable RTP for this exact edition is not confirmed in the reviewed material. Use the active game’s information panel; do not substitute the number from another Mines title.
What should I check before the first round?
Confirm product 546 and read the Treasure Pot rules before a practice stake. Track the main round’s amount separately from the pot indicator. A pot can have contribution, eligibility and reset conditions. Do not add its headline amount to an ordinary cash out.
Can the patterns predict a winning field?
No. The nine fields are randomly generated teaching illustrations. They do not read a server seed, observe a future round or make a particular tile safer. The calculator reports probabilities under stated assumptions.
Does the game’s feature count as a casino bonus?
These are features of the game itself, not a casino bonus. A casino promotion has its own eligible-game list and conditions. Check the named campaign’s participating-game list and contribution rate separately from the in-game feature.
Can I use this demo result at a Canadian casino?
A practice result does not establish regional account access, a casino’s game build, a CAD stake limit or withdrawal eligibility. Match the game information and operator terms for your location before drawing a comparison.
