What are Online Slots?

Definition: Online slots are RNG-based casino games where symbols land on spinning reels and wins are paid for matching combinations.

Main elements of a slot game:

Reels and rows - the grid, e.g. 5 reels × 3 rows.
Paylines or ways to win - the patterns that create a winning combination.
Symbols - regular, wild and scatter symbols.
Feature rounds - special game modes triggered by certain symbols.
RTP and volatility - the game's return and payout distribution.

Common slot formats: classic three-reel slots, video slots with five or more reels, cluster pays slots and games with a variable number of ways to win.

For operators: slots form the core of a casino catalogue and are supplied by game providers through aggregators or direct integrations.
