About the Reel Big Boom Slot Game

This is a 5 reel 3 row video slot game.

The objective of the game is to spin the reels so the symbols land in different combinations.

Winning combinations are highlighted on the reels, and a payout is awarded.

Payline Rules

This game includes 20 paylines.

A payline is a pattern of adjacent symbol positions that runs in a line across the reels.

A win is awarded when matching symbols land adjacent to each other on a payline.

Payline wins run from left to right, starting from the first slot reel.

The number of paylines played is fixed.

Only the highest win is paid per line.

Bet Rules

Each spin played costs a total bet amount.

The initial bet is the current total bet divided by the payline cost of 10.

The total bet is based on the initial bet placed, multiplied by the cost of the paylines played.

Payout Rules

Payline win payouts are based on the initial bet placed.

The payout value is based on the winning combination formed.

If multiple winning combinations land on a single payline, only the highest win is awarded.

Only the highest winning combination is awarded per symbol combination.

The total payout is the sum of all payline wins, and Scatter wins resulting from a spin.

The Paytable displays the payout for each symbol combination based on the current bet.
