Black Gold is a 3D slot by Betsoft. It is equipped with five reels and 30 lines. Four service symbols are provided.
The prize options are represented by a round of free spins and two simple bonus tours. A striking feature is the activation of the respins function and the increase in multipliers after each successful rotation.
How to play Black Gold slot machine
By the rules of the machine, it is allowed to play a game with any odd number of active lines up to thirty. Parameters are adjusted in the Select Lines sector.
The bet size in coins from 1 to 5 is selected in the Bet per Line section. To determine their face value in demo credits, the Choose Coin button is used. Indicators vary in the range 0.02-1.
The function of respins and multiplication of factors
Increasing the frequency of creating combinations and increasing the size of winnings is facilitated by the action of an exclusive prize option. After any successful rotation, the middle reel makes an extra turn. With each respin of the reel, the size of the multiplier increases by one unit. Its maximum indicator is x5.
When this result is achieved, the slot can continue to perform respins until the "empty" turn. Up to this point, all winnings are increased by 5 times.
In the free spins round, the function does not work.
To open access to the round of free spins, you need to catch a combination of 3-5 images with a barn. In this case, the user receives 8 free spins.
During the bonus game, the respins function is disabled. However, the image with the barn acquires the ability of a "wild" symbol, replacing other drawings and multiplying payments.
With the participation in the creation of the first combination, wild picture multiplies its value by 2 times. The size of the payout for the next sequence with a "wild" symbol will be increased already 3 times. The maximum ratio is x10.
Drilling for Oil Click Me and Higher or Lower Bonus Tours
The prize game Drilling for Oil Click Me is extremely simple. It is presented in the classic pick & win format.
To start the tour, you need to collect 3 or more pictures with the image of the drill. The user is invited to select one of them to receive a reward. The player will know what payment is supposed to him only by opening the picture.
To activate Higher or Lower, you need to "catch" 3-5 images of the oil rig. An additional window opens on the screen. The user is offered a game of "more or less."
A specific number is indicated in the field. The user's task is to guess whether the next digit will be more or less than the available one. Correct answers bring rewards.
A user can guess numbers 4 times in a row. The number of attempts does not depend on the correctness of the answers. A player's success only affects the payout amount.
