The game uses a specific set of rules where outcomes are determined by shot charts and a toll mechanism. There are no external accounts, deposits, or real-money cash-outs in this demo. While idle and balance is below 10, pressing Restore sets the balance to 1000, and fractional carry persists across sessions.
Game Structure and Scoring
The game is played over a maximum of six balls (deliveries) with a limit of two wickets. The objective is to reach a specific target score before the innings ends.
- Positive Outcomes: Credit normal runs towards the target.
- Dots (0 Runs): A dot is a ball resulting in zero runs. Every second consecutive dot triggers a toll: it removes three credited runs from the total, floored at zero, and resets the dot counter.
- Wickets: A wicket resets the dot counter but costs one wicket. A second wicket results in an immediate loss.
- Settlement: The innings settles after the sixth ball or upon the second wicket. Reaching the target earlier does not settle the round immediately; all six deliveries must be completed unless the second wicket ends the innings early.
Shot Charts and Probabilities
Four published integer-weight shot charts define the probabilities. The outcomes are: 0, 1, 2, 3, 4, 6, W (Wicket).
- Chart entries are exact integer percentages in the order of these outcomes.
- Random sampling uses unbiased 32-bit rejection into 100 equally likely chart units.
- The coach displays one optimal next action; ties are resolved using the published shot order.
This game has no unlock-token control. The displayed winning multiplier is fixed before the first ball.
Stakes and Modes
The demo supports one active whole-innings stake at a time:
| Stake Options |
|---|
| 10 |
| 20 |
| 50 |
| 100 |
There is no Auto play, cash-out, or extension. The shot policy is adaptive, allowing the player to choose between deliveries based on the coach's optimal suggestion.
Expected Return (RTP) and Math
The expected gross return is 96% under the optimal policy. This is calculated via exact dynamic programming, pricing the selected target at 0.96 / initial_optimal_success_probability.
- 96% is the expected gross return, not a win percentage or a guarantee for every shot policy.
- Measured returns from simulation are sample observations and may vary slightly from the exact expected value.
Mathematical Evidence by Target:
| Target | Optimal Success Probability | Expected Gross Return % | Measured Gross Return % |
|---|---|---|---|
| 8 | 0.7835204659440002 | 96 | 95.977153 |
| 12 | 0.5795584530620002 | 96 | 96.043655 |
| 16 | 0.35191471595000007 | 96 | 96.052454 |
| 20 | 0.16211871519799997 | 96 | 95.981220 |
Wallet and Persistence
Initial Balance: 1000 virtual coins.
- Refill: An idle low-balance refill sets the balance to exactly 1000 when eligible (idle and balance below 10). This is a manual set, not an automatic replenishment.
- Fractional Carry: Fractional balance changes persist through settlement, manual refill, and reload.
- Unfinished Reload: If you reload during an active round, the unfinished round ends without refund or resume.
The balance is stored locally via localStorage. This does not establish anonymity or exclude other processing.
Controls and Interface
Busy Controls: Stake, mode, and refill are locked during active play. Sound remains available.
- Cricket shot choice remains available between deliveries.
- The coach displays the optimal next action based on the current state.
Frequently asked questions
How is the toll applied in Double Dot Toll Over?
Every second consecutive dot (zero-run ball) removes three credited runs from the total score, floored at zero, and resets the dot counter. A positive outcome or a wicket also resets the counter.
What happens if I lose a wicket?
A wicket resets the dot counter and costs one wicket. If a second wicket occurs, the innings ends immediately with a loss. The game allows up to six balls, but the second wicket triggers early settlement.
Does the demo require an account or login?
No. This is an independent guide's demo. There is no account login flow, no deposit, and no real-money cash-out. The balance is managed locally within your browser session.
