Game Mechanics and Payouts
The game displays four independent tiles, each showing one of three equally likely shapes. Players count matching adjacent pairs across the three seams between tiles. Each match returns a gross payout of 0.96 times the stake. The total possible returns are 0, 0.96, 1.92, or 2.88 times the stake. The expected return is calculated as three times one-third times 0.96, equaling 0.96.
Stakes and Wallet Rules
Available stakes are 10, 25, 50, and 100, with 25 as the default. The captured stake is deducted once at the start and persists before animation. Gross returns include the stake, with fractional carry saved separately. Whole coins are credited by flooring the result, while the remainder up to 99 hundredths is kept. A manual refill restores the balance to 1000 only when idle and below 10.
Settlement and Controls
Settlement is automatic upon exit or reveal completion, with no manual stop or autoplay options. Reloading the page discards any unfinished round without refund or resume. Controls for stake, start, and mode are disabled while active. The game uses localStorage to save the wallet and pending flags, but does not require an account for the demo.
Frequently asked questions
Is IPO138 a verified operator?
IPO138 is an unverified brand. The demo uses virtual coins with no cash value, and external login buttons do not establish affiliation or verified support channels.
How does the wallet restoration work?
Manual restoration sets the balance to 1000 only when the user is idle and the balance is below 10. It does not add to the current balance but resets it entirely.
