Terms for this browser demonstration

Scope of these demo terms

These terms explain this free browser demonstration, its virtual wallet and the limits of this guide. They do not establish an outside company’s terms, identity or legal status. Using the demo does not open a real-money account. The displayed game rules apply to the board played here.

How the six assignments work

Leximin Assignment draws nine independent values, each equally likely to be 0, 1, 2 or 3, in a 3 × 3 board. An assignment selects one cell from each row and uses each column once. There are six assignments. Sort each selected triple from smallest to largest, then compare the triples: prefer the larger first value, then the larger second value if the first ties, then the larger third value if both tie. The middle value of the winning triple is the raw reward s, from 0 to 3. This compares assignments across rows, rather than sorting each row separately.

Reward powers and gross return

Reward power 1 uses s, power 2 uses s², and power 3 uses s³. Each weight has its own exact mean μ over all 262,144 equally likely boards. The gross multiplier is 0.96 × sᵖ ÷ μ for the selected power p; multiply it by the captured stake for the raw gross payout. Each mode therefore has a 96% expected gross return in the mathematical model. This is an average over the full distribution, with no guarantee for a board or session. Gross return includes any stake recovered; it is not net profit.

The exact mean weights for powers 1, 2 and 3 respectively are 606681/262144, 1520669/262144 and 4021275/262144. Each is the average of its own powered raw rewards, before multiplying by 0.96.

Starting and finishing one board

Choose a stake of 10, 20, 50 or 100 virtual coins and reward power 1, 2 or 3, then press “Draw one board”. A new page load selects stake 20 and power 1. Starting a funded draw captures those choices, draws the whole board and deducts the stake once. Stake, power, restore and start controls are unavailable while the draw is active; sound remains available. There is no automatic queue, Stop button, intermediate collection or early cash-out.

Restoring the virtual wallet

The first wallet starts at 1,000 virtual coins. When no draw is active and the balance is strictly below 10, “Restore balance” sets it to exactly 1,000. It does not add 1,000, refund earlier stakes or start a draw. The fractional remainder, selected stake and selected power stay unchanged. A balance of exactly 10 is not eligible. Restoration is optional and never automatic.

Saved balance and unfinished draws

The wallet balance, including zero, and fractional remainder are saved in browser localStorage. The stake deduction at the start of a draw is saved too. Reloading an unfinished draw loses its pending result: there is no refund, payout or resumption. The saved balance and previous fractional remainder remain, while stake and power return to 20 and 1. Saved wallet values do not provide an account recovery service.
