Slot bonus types, explained

Six original games open up the rules: start with how each bonus pays, then follow the examples through its odds and expected return.

Where does each game's return come from?

These six practice games have similar overall returns, but distribute their awards differently. Base return means line awards on paid spins, including a spin that triggers a bonus. Bonus return includes every later free spin, respin, offer and wheel award earned by those wagers.

Exact model calculations with all earned features completed. Figures are rounded.

Lanternfox Market35.36%60.09%95.45%63.0%1 in 23.72

The bonus share is bonus return divided by total return. For Lanternfox, 60.09 ÷ 95.45 is about 63%, so almost two thirds of its expected return arrives during features. That helps explain why bonuses matter so much to its results. It is not a volatility score: the size, frequency and spread of individual awards also determine how much a session can swing.

Frequency counts a bonus starting on a paid spin, with retriggers and bonuses inside free games excluded. Orbit's combined rate counts a spin that triggers both features only once. Its separate paid-spin rates are about one Hold & Spin per 114.71 spins and one free-game feature per 128.42 spins. None of these averages is a countdown.

*Copper Canyon's row assumes the accept-or-replace policy that maximizes expected return. Always taking the first offer lowers its total RTP to 78.67%, a difference of about 16.55 percentage points. The offer decision guide shows why each choice matters.

Copper Canyon and Velvet Sevens share their base reels and paytable, so their different bonus rules explain the change in total return. Neon Relay shares the reels but changes three line awards as well. These are our original practice models, not RTP claims about commercial games with similar features.
