The so-called risk game is available in many video slots of various types. It is also called a game of equal chances or doubling round, although sometimes you can not only double the payout, and the probability of winning is not always 50: 50.

It is usually called Gamble or Double Up, but there are also other variants. It is used not only in slots. For example, it is common in video poker. But in this article, only slots are considered.

Let us give a general definition of the term:

A double-up game is a round triggered at the client's request, in which he can try to increase the amount of the payout received during the spin or in some other way.

In other words, the user can activate this function if he has won any amount. During the draw, he can multiply it or lose money.

The rules of this round, its essential versions, unusual variations, additional features, and pitfalls are discussed below.

Double-Up Game Variants

There are several main variations of the risk game. In addition, some software developers offer unusual types, sometimes surprising with their non-standard approach and creative thinking.

First, let's discuss the basic types:

  • Card color is a widespread option used by most video slot manufacturers. It is necessary to guess what color the next card in the deck will be. The correct answer doubles the payout. The wrong choice deprives the player of the money at stake.
  • Card suit – Usually, this option accompanies the "card color" option. The client can try to determine the suit of the card. If he succeeds, the payout is quadrupled.
  • Beat the dealer – This version is typical for video poker but is also used in many slots. The client chooses one of the cards at random. If he beats the virtual dealer's card, the winnings are doubled. You can also lose money or draw the round. Interestingly, some providers allow you to withdraw from the draw after the user sees the card dealer. This will enable you to play only in the most favorable situations.
  • Coins – These varieties are also called "heads or tails". The point is to defeat the conditional opponent, guessing which side the coin will land on. Betsoft and some other developers offer very colorful solutions round. The client is usually confronted by the slot's main character appearing on the additional screen.
  • Ladder – This kind is straightforward. The player climbs the steps. At each stage, he can either increase the payout or decrease it. If he gets to the bottom, he loses the bet. If he gets to the top, he will get the maximum win. Sometimes checkpoints are available, meaning a guaranteed victory of a certain amount.

Some brands offer two types of rounds to choose from. For example, in the devices, Bally Wulff is "guess the color" and "movement on the stairs."

Now let's talk about the unique varieties of the game on doubling.

  • Thematic lotteries – As a rule, they are stylized variations of the classic rounds of doubling. For example, the developers mentioned above from Betsoft allow fighting in the eagle with the characters of slot machines.
  • Author varieties – Some manufacturers are looking for non–standard approaches. A striking example is the untamed series models by Microgaming dedicated to wildlife. They present a unique risk game. The client must set the sector on a unique scoreboard, determining the chances of winning and the amount of potential payout.

All reviews of slots at Casinoz consider the game's features on equal chances in this model. One paragraph is devoted to it if it is conducted according to classical rules. If we are talking about an unusual version, the round is described in more detail.

Money at Stake

The user can wager all the money he received during the previous spin in the double-up game. This is the most common but not the only approach.

Many providers allow betting half the amount. In rare cases, it is allowed to change the bet in the risk game. In other words, it can be arbitrary.

Various Limits

In almost all slots, you can play the double round several times in a row, but there are usually different types of restrictions.

  1. Limits of attempts – Many developers allow you to play no more than a certain number of times in one session, but some providers refuse this practice.
  2. Payout limits – the maximum amount that can be won during the round, stipulated in the rules of the vast majority of machines. Usually, it is tied to the rate.

Carefully read the terms of the risk game to avoid misunderstandings.
