Octoplay studio has prepared a great online pokie Big Bang Bonus Hold & Win for its upcoming release. The game features simple rules, exciting gameplay and a well-balanced bonus feature. Graphics is not too outstanding, but it is quite enough to realize the mining theme. Sound accompaniment does not cut the ears, and optimized machine at a decent level.
In the pokie we can find Hold&Win respins, accumulative and familiar trigger, bonus upgrade system and paid Double Chance feature. At first I thought that I would have to deal separately with the level upgrade. As it turned out - everything happens gradually, as the respins are activated. As a result - in just 20-30 minutes of playing time we already get the best multipliers and awards. It is worth giving the machine credit, it is quite generous. Despite the low volatility, the size of the winnings sometimes makes you surprised. Yes, and maxwin is not pumped up, because it can reach x5050 of the bet. Some people may find the gameplay too boring. Mol, all this has already been realized earlier, in dozens of other machines from different manufacturers. But after all, the mathematical model is different for everyone! Before abandoning the game, you should at least play it for a while in the demo version. I think that the slot will be liked by many gambling fans and especially by beginners.

In the normal game mode we are waiting for a 5x4 playing field with 20 fixed lines for making combinations. To get the winnings we will need 3+ identical symbols located from left to right on the paid direction. Wild symbols will simplify the task. The stake is chosen by the player, but only from the range of 0.1 to 100 c.u.. The pokie has 9 basic and 3 special symbols. The whole gameplay is built around the Hold&Win respins system. In the normal game mode bonuses are not available.
During the respins we collect prizes from the money symbols, can catch one of the jackpots, and Mystery symbols delight with instant wins.
I quite enough such functionality in the pokie machine to get their portion of excitement and pleasure. It would be possible to slightly diversify the usual game mode, at least a random bonus. But if the provider considered it unnecessary, then he had his reasons.
Jackpots can fall during Hold&Win Respins, in the form of gems. All of them have fixed values, which can be increased by a multiplier per dynamite level:

In Big Bang Bonus Hold & Win pokie, as in other pokies, there is no guaranteed winning strategy.
The game is based entirely on a random number generator, which eliminates the possibility of predicting the results and the use of any tactics. All a player can do is to manage his bankroll wisely and try to reduce his risks. Success comes thanks to certain betting systems, personal experience and faith in luck. However, there is no universal scheme for stable winnings and it is unlikely to ever appear, because it would contradict the very idea of pokies.
