Coin Craze: Supercharged Slot Review

In 2003, a study from the University of Michigan found that people make better decisions when they need to use the bathroom. 🚻 Apparently, the physical sensation of needing to hold something carries over to the mental act of holding back an impulse.

Bladder control as a life strategy? Nobody saw that one coming. Scientists called it "embodied cognition." The rest of us call it "accidentally good advice." 🙈 Anyway, the point is that sometimes a little tension and a little pressure can sharpen things up.

Which brings us neatly to Coin Craze: Supercharged slot from Mancala.

Gameplay

No paylines, no spinning reels loaded with Cherries and Bells, no Wilds doing wild things. This game strips the format right back to a 5x3 grid where the only thing that matters is what lands on the middle row and what turns up during the Bonus Game.

There are 4 Jackpots up for grabs, and they are displayed at the top of the screen: 10x Mini, 20x Minor, and 50x Major. The Grand Jackpot sits at a live value, and it's available if you fill the entire grid during the Bonus Game.

In terms of the stats running the show: a 95% RTPRTP stands for “Return to Player.” The RTP describes the total bet amount that a game returns to players over millions of spins, and that figure is represented by a percentage. Table games, such as Roulette, typically have higher RTPs than many slots.

RTP needs to be considered in conjunction with a game’s volatility rate., very high volatility, a 7,000x max multiplier, and a $140,000 max win.

Features

CLAIM WIN

Claim Win can appear in any position during the base game. Once it lands, it sits there and collects values from that position with every spin, counting down until it cashes out. The payout is a percentage of everything collected: 10%, 20%, 30%, 40%, 50%, 100%, 150%, or 200%.

STICKY SYMBOL

Sticky symbols can appear during the base game and remain on the reels until the Bonus Game ends. If they're part of a Claim Win feature, their value keeps building with every spin until the counter runs out.

BONUS GAME

When you land any 5 symbols on the middle row, you’ll trigger the Hold and WinThis feature plays out on a new screen. Typically, you get 3 re-spins (which could be re-triggered), and the triggering symbols usually stick to the position on which they land. Your objective is to land as many symbols as possible on the grid (you could land blank tiles, too). Bonus Game. You start with 3 spins, and every new symbol that lands resets the count. The round ends when you’re out of spins, or when all 15 positions on the grid are filled.

If you fill the entire grid, the 7,000x Grand Jackpot is yours. Worth knowing: when you win the Grand Jackpot, all other prizes are forfeited.

JACKPOT SYMBOLS

Jackpot symbols (10x Mini, 20x Minor, 50x Major) appear in any position during both the base game and the Bonus Game. In the base game, they only pay via the Claim Win feature. During the Bonus Game, more than one Jackpot of each type can be won in the same round.

In addition to Jackpot Coins, there are also Silver Coins (1x-10x) and Gold Coins (5x-15x).

COLLECTOR SYMBOL

The Collector symbol can appear in any position across both game modes. During the Bonus Game, it accumulates all existing coin values on the grid, then multiplies the total by a random amount between 1x and 20x, without removing any of the symbols.

The coins stay in place and keep their values. That distinction matters: a well-timed Collector hit on a grid already loaded with high-value coins and Jackpots can produce a serious spike.

MULTIPLIER SYMBOL

Only available during the Bonus Game. The Multiplier symbol applies a 2x boost to all values on the grid, except for the Grand Jackpot trigger.

SURPRISE SYMBOLS

You’ll come across two types of Surprise symbols. The standard Surprise symbol awards a random reward during the Bonus Game, then transforms into any symbol except a Jackpot Surprise or a Sticky symbol.

The Jackpot Surprise version awards a random Jackpot (Mini, Minor, or Major), but cannot give you the Grand. After the bonus, it transforms into any Jackpot symbol except the Grand.

BUY BONUS

There’s a Buy Bonus available, located in the top-right corner. Players can pay 93x to trigger the Hold and WinThis feature plays out on a new screen. Typically, you get 3 re-spins (which could be re-triggered), and the triggering symbols usually stick to the position on which they land. Your objective is to land as many symbols as possible on the grid (you could land blank tiles, too). on your next spin.

Performance

Everything worked great during testing, and there are no issues to report.

Maximum Win

Players can bet between $0.10 and $20. Hit the 7,000x max multiplier on a $20 bet, and the $140,000 max win is yours. That requires filling all 15 positions on the grid during the Bonus Game to claim the Grand Jackpot.

Conclusion

Two things decide how your Bonus round pays out: how much is on the grid when the re-spins start drying up, and whether the Collector shows up while it's still loaded.

A Collector landing on a thin grid with a couple of low-value coins doesn't do much. The same symbol on a grid with Major Jackpots and high Regular Coins, multiplied by up to 20x, that's a different result entirely.

The Grand Jackpot trade-off is an interesting one, and worth thinking about before you get there. Filling all 15 positions hands you 7,000x, but all other values on the grid get wiped.

If you’re already sitting on a strong spread of Jackpot coins and a Collector has already landed, pushing for the full house means giving all of that up. Sometimes the grid you have is actually the better outcome.

Don't ignore the Claim Win feature either, especially when it has a Sticky symbol. That combination builds quietly across multiple spins, and if the payout percentage hits 100% or above, it should payout nicely without the Hold and WinThis feature plays out on a new screen. Typically, you get 3 re-spins (which could be re-triggered), and the triggering symbols usually stick to the position on which they land. Your objective is to land as many symbols as possible on the grid (you could land blank tiles, too). even being involved.

The 93x Buy Bonus gets you in right away, but it doesn't change what happens once you're there. Very high volatility means some Bonus rounds will end with three symbols on the board and nothing to show for it. Try to budget for several buys, not just one.

Getting your hands on the 7,000x max means getting into a Bonus round where new symbols keep landing fast enough to keep the spin-counter alive, the Collector lands with a stacked grid, and the last few positions fill before the spins run out.

Patient players at lower bets will get there eventually. Anyone using the Buy Bonus regularly needs a bankroll that doesn't flinch at a few quiet rounds first.
