What Are Slot Symbols?

There are two types of symbols in online slots. The first ones are ordinary. They are necessary to form paid lines. That is, they have one function – to give the player winnings if the conditions for their accrual are met. The condition may be to collect identical symbols on one of the lines, to obtain a cluster or a certain number of such symbols on the field.

Slot bonus symbols don’t always take part in a paid combination. They may not be taken into account at all when forming lines. They have a different task – to make the gameplay more diverse. Bonus symbols can give an additional multiplier, activate free spins, re-spins, open new reels, play a jackpot, etc.

Ordinary slot symbols form paid lines, while bonus symbols add diverse features.

Slot Symbols History

The first slot machine in history was developed by American engineer Charles Fey at the end of the 19th century. It was a simple mechanical slot called Liberty Bell. It had only one row and three reels. To get a win, the same symbols had to appear on two or three reels, starting from the first.

Like dozens of others in the future, this slot machine used symbols of card suits, diamonds and horseshoes. The image of a bell was considered the most valuable. These symbols have become classics, and for many years, until the mid-20th century, they could be found on most slot machines.

Later, symbols of fruits and berries were added to them. However, both these and the symbols described above were not bonus symbols. The only function they performed was the formation of paid lines.
