A multi-coin/multi-line slot is a type of slot machine with several paylines and multiple coins. This type of slot machine usually has a number of different features that can increase your winnings. Some of these features include Buy-a-pay, Scatter symbols, and Multipliers. Learn what they are and how they can help you win big.

Multi-coin/multi-line slots

Multi-coin/multi-line slots have many paylines, which increases the chances of winning. While older slot machines usually only had a single payline, modern machines may have 20 or 40 paylines, with bonus levels, wild symbols, multipliers, and even progressive jackpots. You can also select different ways to win in multi-coin/multi-line slots, including high-low mode, which allows you to pick symbols that are close to the maximum value.


A buy-a-pay slot machine is a machine that allows you to buy pieces of potential payouts with each coin you insert. For example, with one coin, you can unlock the middle line of the reels. If you hit three symbols on this line, you will win a payout.

Scatter symbols

Scatter symbols are symbols that can be found on the reels of a slot game and can unlock special features. These features often include free spins, bonus rounds, and interactive mini-games. The more scatter symbols you can land on the reels, the higher your payout will be. Before you play any slot game, make sure you check the paytable to learn which symbols are scatters. In some cases, you can even trigger a bonus game if you land on three or more scatter symbols.


Multipliers in slot machines are an excellent way to boost your chances of winning big. These bonuses often double or triple your initial bet value, and some of them even allow you to win up to 1000x your initial bet! These bonus features vary from game to game, so it’s important to read the pay table for any slot before you start spinning the reels.

3D slots

3D slots are gaining popularity as a way of presenting exciting and innovative gameplay to players. They offer eye-candy graphics, entertaining storylines, and hefty bonus amounts. However, players should be careful about playing these games as they can quickly become addictive.

Return to player (RTP)

The Return to Player (RTP) percentage of a slot game is an important barometer of how likely it is to win. The percentage of a game’s return to player will vary depending on the number of lines and selections made. These figures are based on millions of spins and should be treated as a guide only.
