Grand Heist Feature Buy Slot Overview

Grand Heist Feature Buy is a new casino slot from OneTouch, updating last year’s Grand Heist with a Bonus Buy and other features. The objective is the same, making cluster wins of 5 or more symbols on the 8x8 grid. The goal is to empty the vast bank vault with the help of jumping wilds, colossal symbols, and growing multipliers. Robbing the bank has never been as exciting, and the max win has been raised from 3500X to 12000X the bet.

Base game

Grand Heist Feature Buy is a video slot from OneTouch with 8 reels and 8 rows. There are no regular paylines; players will instead make wins by landing 5 or more symbols in connected clusters. The Min.bet is 0.4, and the Max.bet is 100. Grand Heist Feature Buy has an RTP of 96.14% and high volatility. The perfect bank hit will result in the max win of 12000X the bet.

You will find valuable help in and around the bank vault in the form of the features Cascading Wins, Wild Symbol, Giant Symbols, Free Spins, and Bonus Buy.

Grand Heist Feature Buy Slot Information

Grand Heist Feature Buy takes place in a modern bank vault with silver-colored walls and a pink roof. To the left is a giant vault door, and to the right is a big hole where we suppose another door used to be. The grid is packed with 64 rather small symbols on the 8 reels and 8 rows. To land a win, you need to land 5 or more symbols in a cluster, connected either horizontally or vertically. Symbols on a diagonal line don’t make up any win. OneTouch is known for creating slots for mobile phones, and Grand Heist Feature Buy is no exception. However, you can also play it on notepads and desktop computers.

The game has 6 regular paying symbols. The lower-paying ones are casino chip, watch, and gold bars. Landing a 5-of-a-kind win with them will award between 0.1X and 0.15X the bet, and 25 or more symbols will award 10X-25X the bet. The higher-paying symbols are gold egg, button, and crown. These symbols pay between 0.25X and 1X the bet for a 5-of-a-kind win and 37.5X-100X for a win containing 25 symbols or more. The Wild Symbol substitutes all symbols and triggers the free spins if 3 or more land on the same spin.

Grand Heist Feature Buy Slot Features

What is the max win in the slot Grand Heist Feature Buy?

You can win up to 12000X the bet.

What features are available in the slot Grand Heist Feature Buy?

The features are Cascading Wins, Wild Symbol, Giant Symbols, Free Spins, and Bonus Buy.

Free Spins

Cascading Wins

Every time you make a win, the involved symbols will disappear while new ones rain down. If you’re able to make a new win, the involved symbols will once again vanish while new ones fill up the grid. The cascades go on as long as you keep making wins, and they all belong to the same spin.

Wild Symbol

The Wild Symbol is a package of explosives substituting all other symbols. It can appear anywhere and stays on the grid during cascades if it’s involved in a win. It will randomly move to an adjacent vacant position, where it stays for the following cascade. Each Wild has a multiplier starting at 1X, increasing by 1 for every win it takes part in. If 2 or more Wilds are involved in a win, their values will be multiplied by each other before it’s multiplied by the win. Landing 3 or more Wilds anywhere triggers 8 free spins.

Giant Symbols

Giant Symbols in the size of 2x2, 3x3, or 4x4 can land anywhere on the reels. After a Giant Symbol has landed, it’s divided into regular-sized symbols of the same kind.

Free Spins

Landing 3 or more wilds anywhere triggers 8 free spins. The feature is similar to the regular spins, except that the wilds’ multipliers never reset between spins. All wilds stay on the reels during the entire feature. The feature is over when the player runs out of spins.

Big Win

Bonus Buy

You can choose to buy the free spins in two different ways. Paying 69.5X the bet will get you the triggering spin with 3 wilds randomly placed on the grid. For 166.5X the bet, you’re guaranteed that the wilds will be adjacent to each other, wherever they end up. 

Grand Heist Feature Buy Slot Conclusion

Grand Heist Feature Buy’s advanced bank vault is a perfect casino slot location. Some players might find it a little hard to keep track of all 64 symbols, which are pretty small to fit the screen. It helps a lot that there are only 6 regular symbols and the wilds on the reels, though. The symbols are also created in distinctive shapes and colors to help separate them easily. In the mobile version, one of OneTouch’s specialties, the vault looks even better with a pink-purple light.

Grand Heist Feature Buy is actually really easy to follow when you get the hang of it. Other cluster-win games, like Cyberslot Megacluster or Star Clusters Megapays, where the reels and rows expand during the game, are harder to follow. The cascading wins can result in pretty nice wins, especially if there is a wild with a growing multiplier. In the free spins, they become even better, where the wilds multiply their multipliers by each other before multiplying the wins. The RTP of 96.14% is about standard, and the max win of 12000X the bet is good but far from exceptional for a highly volatile slot.

Grand Heist Feature Buy from OneTouch takes the player to a bank vault where the objective is to steal as much money as possible with the help of cascading wins and wilds with progressive multipliers.
