Red Hot 20 uses a left-to-right payline system, with players able to activate between 1 and 20 payoff lines. Winning combinations are formed by landing 3, 4, or 5 identical symbols on an active line.
The flexibility in line selection allows players to tailor risk and stake size to their preferences. Activating more paylines increases winning chances, while fewer lines allow for more controlled betting sessions.

How to Play
Red Hot 20 is simple to play and offers flexible betting controls suitable for beginners and experienced players alike.
Before spinning the reels, players can adjust the following settings:
- Number of Paylines: Choose between 1 and 20 using the Line menu
- Bet per Line: Select a value between 1 and 100 credits using the Bet/Line menu
The total bet per spin is calculated by multiplying the bet per line by the number of active paylines. The Credit display shows the current balance, while the Paytable button provides detailed information on symbols and payouts.
Press Start to spin the reels manually or activate Autoplay for automatic spins without repeated input.

This feature adds a layer of excitement and strategy, allowing players to turn smaller wins into more substantial payouts. It is best used selectively, especially when aiming to boost modest rewards.
