RTP & House Edge Explained

Return to Player (RTP) is the percentage of all wagered money that a game will pay back to players over time. For example, a slot with an RTP of 96% will — on average — return Rp 96 for every Rp 100 wagered across millions of spins. It is a statistical long-run figure, not a per-session guarantee.

The house edge is the mathematical inverse of RTP. A game with 97% RTP carries a 3% house edge — meaning the platform retains 3% of all wagers over time as its operational margin. Understanding these figures before playing is an important part of responsible, informed gambling.

Different game categories carry significantly different RTP ranges. Skill-influenced games like blackjack typically offer the highest RTPs when played with correct basic strategy. Pure RNG slots tend to have wider variance and wider RTP spreads depending on the studio and title. koi155 publishes individual game RTPs in each game's information panel.

Typical RTP Ranges by Game Type

Blackjack (Basic Strategy)~99%
Video Poker97–99%
Baccarat~98.9%
European Roulette~97.3%
Live Dealer Games94–98%
Online Slots (High RTP)95–98%
Online Slots (Standard)92–95%

All figures are industry-standard ranges. Individual game RTPs may vary by title and provider. Verify each game's RTP in its in-game paytable or information panel.

Account Verification Process (KYC)

KYC (Know Your Customer) verification is a standard security requirement across all legitimate international betting platforms. On koi155, it takes as little as one hour.

1
Why KYC Is Required

3
Submission & Review

Upload documents via the secure verification portal in your koi155 account dashboard. Our compliance team reviews submissions around the clock — typical processing time is 1–24 hours (WIB).

4
