The first and main goal of the demo mode is to give you the opportunity to learn how to play without the risk of losing money. Here are some important features:
Statistics. In some games, you will be able to view statistics from previous rounds, both yours and those of other players.
Demo bet. During the demo mode, you will be credited with a certain amount of virtual money. They cannot be withdrawn, as well as winnings in this mode, but they will be more than enough for training.
Auto play. Most Mines games will have an auto mode with a large number of settings. You can specify the number of mines, the number of cells to open, the conditions for ending the game, and more.
Turbo mode. Some games offer Turbo mode. Its specificity is that you immediately specify the number of mines and select cells, and after the bet, they all open at the same time. If at least one has a mine, you lose.
Multiplier. Each time you successfully open a cell, your multiplier increases slightly. You can initially increase the numbers of your multipliers by choosing a larger number of mines. But this will also affect the risk in the game.
