The Double-Up Feature in Slot Machines

What Is a Double-Up Feature in Slot Machines?

Let us give a general definition of the term:

A double-up game is a round triggered at the gambler's request, in which they can try to increase the payout received during the spin.

In other words, players can activate this feature if they have a payout. During the round, they can multiply the money or lose it.

Double-Up Game Variants

There are several main variations of the Gamble 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:

• "Guess the card color" is a widespread option most video slot manufacturers use. The player must guess the color of the next card in the deck. The correct answer doubles the payout, while the wrong choice deprives the player of the money at stake.
• "Guess the card suit" is an option that often accompanies the "card color" option. The customer can try to determine the suit of the card. If he succeeds, the payout is quadrupled.
• "Beat the card" is typical for video poker but is also offered in many slots. The gamblers choose one of the closed cards. If it beats the open card, the winnings are doubled. You can also lose money or draw the round. Some providers allow you to withdraw from the draw after seeing the card. This will enable you to play only in the most favorable situations.
• "Heads or Tails" is also a popular option. The point is to guess which side the coin will land on. Betsoft and some other developers offer very colorful versions of this game. The player is usually confronted by the slot's main character appearing on the additional screen.
• "Stairs"  is a very straightforward game. The player climbs the stairs. At each step, they either increase or decrease the payout. If they get to the bottom, they lose the bet. If they get to the top, they will get the maximum win. Sometimes, checkpoints are available, meaning a guaranteed victory of a certain amount.

Some brands offer two types of Double-Up rounds. 

Now let's talk about the unique varieties of the Double-Up game in online video slots.

• Thematic games are usually stylized variations of classic Gamble rounds. For example, Betsoft offers to play heads or tails against the main characters of slots.
• Several manufacturers offer unique slot varieties, embracing non–standard approaches. One striking example is Microgaming's Untamed series, dedicated to wildlife. This series presents a unique risk game. The client must set the sector on a scoreboard, determining the odds of winning and the potential payout amount.

All slot reviews on Casinoz consider the rules of Double-Up games. If it is a classic version, the description is short. Unusual versions are described in more detail.

Money at Stake

The user can wager all the money 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, you can change the bet in the risk game. In other words, you can bet any part of your payout.

Maximum Betting Limits

In almost all slots, you can play the double round several times in a row, but there are usually some 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 do not set such limits.
2. Payout limits: The maximum amount that can be won during the round is specified in the paytable or Help section. Usually, it depends on the bet size.

Carefully read the terms of the Double-Up game to avoid misunderstandings.
