Irish Riches Bonanza

Irish Riches Bonanza Slot Review

Irish Riches Bonanza by 18Peaches is a 7 by 7 grid game that uses cluster wins instead of classic lines. You get cascades, wilds, multipliers, free spins, and a couple of ways to boost your bonus chances.

Layout, bets and basic info

The game plays on a 7 row by 7 reel grid. There are no fixed lines. Instead, wins come from groups of matching symbols that touch side to side or up and down.

You can usually bet from around 0.20 per spin up to a high limit that reaches 200, so it works for small and big bankrolls. The stated return to player is 95.74 percent and the game leans toward the high side of volatility, so big hits are possible but not constant.

Cluster pays system

There are no paylines here. To get a win, you need a cluster of at least five of the same symbol touching horizontally or vertically. The more symbols in the group, the higher the payout.

Clusters can form anywhere on the grid. You are not forced to line things up from the left. This makes the game feel more like a puzzle grid than a classic reel slot.

Cascading wins

When you land a winning cluster, all those symbols are removed from the grid. New symbols then drop down from above to fill the empty spaces. If the new symbols create another winning cluster, they are also removed and more symbols fall in.

This cascade keeps going as long as you keep forming new wins from a single paid spin. One spin can chain into several payouts in a row, which is where a lot of the excitement comes from.

Wild symbols

Wild symbols can stand in for regular pay symbols to help complete or improve clusters. If you are one symbol short of a group, a wild can often bridge the gap and turn a near miss into a win.

Wilds do not usually replace scatters, so they help with line wins but not with triggering the bonus round.

Random wilds

On some spins, the game can drop extra wilds onto random positions on the grid. This can happen in the base game to shake up a dead spin and give you a better shot at building a big cluster.

Because the slot uses cascades, random wilds can start a chain reaction. A single boosted spin can turn into several wins if the new wilds keep linking up with matching symbols.

Scatter symbols and triggering free spins

Special scatter symbols are used to trigger the bonus round. You do not need them in any set order or position. As long as enough scatters land anywhere on the grid on the same paid spin, the feature will start.

You need four scatters at once to unlock free spins. When that happens, you are awarded 10 free spins to begin with. Extra scatters above the fourth can add more starting spins, depending on the configuration your casino uses.

Free spins feature

Free spins play on the same 7 by 7 grid with the same cluster and cascade system, but with extra power added on top.

During the feature, landing three or more scatters again will retrigger and give you more free spins. This means a single bonus round can last a long time if you keep seeing scatters drop in during cascades.

Multiplier system in free spins

The big twist in the bonus round is the multiplier system tied to wilds. In free spins, special wilds can carry multipliers. When they are part of a winning cluster, they boost the payout for that win.

These multipliers can range from small values like 2 times up to very high values that can reach 100 times. If more than one multiplier wild is involved in the same winning cluster, their values can stack together so the total boost can get huge.

Because wins can cascade, you can hit several boosted clusters in a row during a single free spin. This is how the slot reaches its top win potential of up to 5,000 times your bet.

Double chance feature

The game offers an optional extra bet mode often called double chance. When you turn this on, your stake per spin increases, but in return the game adds more scatter symbols into the symbol pool.

With more scatters on the grid, your odds of triggering the free spins round go up. It is useful if you mainly care about hitting the bonus and do not mind paying a bit more per spin to chase it.

Bonus buy option

If you do not want to wait for scatters at all, there is a bonus buy button in some regions. For a fixed cost of 100 times your current total bet, you can buy instant entry into the free spins feature.

When you buy the bonus, the game jumps straight into the free spins round with the usual number of starting spins. From there everything plays out normally with cascades, wild multipliers, and retriggers.

Gamble feature

After some wins, you may get the option to gamble your payout. This is a separate screen where you risk your recent win for a shot at increasing it.

The gamble is usually based on a simple choice, like guessing the color of a hidden card. A correct guess doubles your win, while a wrong guess makes you lose the amount you just risked. You can often repeat the gamble a few times or stop and collect at any point.

Progressive jackpot

The game supports a progressive jackpot in some setups. This means a small part of each bet can feed into a shared prize pool that keeps growing until someone wins it.

How the jackpot is triggered can vary by casino. It might drop at random or need a special symbol combination. If it is active, you will usually see the current jackpot value displayed above the grid.

Autoplay and quickspin

The slot includes autoplay, so you can set a number of spins to run on their own with your chosen bet. There are often simple controls to stop autoplay when you hit a certain loss or win limit.

Quickspin can also be enabled to speed up the animations. This makes each spin resolve faster, which is handy if you like a brisker pace or are grinding for a bonus.

Win potential and volatility feel

The maximum win is capped at 5,000 times your bet. With a return to player of 95.74 percent and a higher volatility profile, the game tends to play in swings.

Thanks to the cluster system and a hit rate close to half of all spins, you see wins fairly often, but many of them are small. The bigger hits usually come from long cascade chains in free spins when wild multipliers line up just right.
