Skyline : High-Cap Slot Features in One Room

A prize tier is a fixed reward level built into the slot's base mechanic — usually labeled Mini, Minor, Major, or Grand — triggered by specific symbol combinations during a spin.

Volatility describes how often a slot pays out relative to the size of each payout. High-volatility titles pay less frequently but with larger amounts; low-volatility titles pay more often but smaller.

RTP (Return to Player) is the percentage of total wagers a slot returns over a large number of spins. It is a long-run statistical figure — not a session promise or a per-spin prediction.

Scatter pays award a prize when a set number of scatter symbols land anywhere on the reels — not on a specific payline. Sweet Bonanza, for example, uses this mechanic for all of its payouts.

A feature round is a triggered bonus phase inside the slot — usually free spin sequences or multiplier events — that runs separately from the base game and can increase the size of the prize outcome.

Stacked symbols are identical icons that fill two or more positions on the same reel column. When stacks align across reels, they can form large cluster wins or trigger multiplier chains.
