A game guide on slot machines should offer its reader a number of specific points. The RTP of the game is important. This is the perceived return to player percentage which the slot machine will pay out over a specified period. Why does it matter? Because it gives you some idea what to expect regarding payments from the video slot. The reverse of the coin is the remaining percentage, known as the house edge in table games. So a 97% RTP has a house edge of 3%.

The higher the RTP, the better your return rate over time, so a good playing strategy is to choose those above 97% RTP. Alongside introducing to you to the type of game you are playing, 3-reels, 5-reels, fruit slots, classic slots, themed slots; a good game guide will indicate the bonuses and individual characteristics of each online slot. It will also let you know if it is a progressive slot. Here, a percentage of all bets will be combined from a number of machines or casinos, offering the winner some life-changing jackpots.

Something else a player needs to know is the volatility of a game, not to be confused with the RTP. There are low, medium and high volatility games and knowledge of what these are can save your bankroll from quickly disappearing.
