Mirage City

Mirage City Slot Review

Mirage City by Ace Roll drops you into a desert festival with neon lights, fireworks, and a rave style soundtrack. Under the party look there is a pretty serious math model, with high volatility and a strong focus on growing reel multipliers and expanding wilds. The setup is a 5 by 5 grid with 15 fixed lines and bets from 0.10 up to 75 per spin. The top return to player is 96.31 percent when set to the highest configuration.

Theme, visuals and symbols

The game is set in a temporary city in the sand, with tents, bikes and a sunset sky in the background. The reels are framed in neon, and fireworks and light beams kick in when features start to build. The low paying symbols are 10, J, Q, K and A in glowing purple. The high pays are four character symbols that represent different festival goers. Five of a kind royals pay from 1 to 2.5 times your bet, while five of a kind premiums pay from 5 to 10 times your bet.

The wild symbol is the most valuable regular symbol. A full line of five wilds pays 20 times your bet. Wilds also substitute for all regular pays to help complete winning lines.

How wins and expanding wilds work

Mirage City uses a simple 15 line layout. You win when three to five matching symbols land in order on a payline from the leftmost reel. When a wild symbol is part of any winning line, it does something special. Instead of staying as a single position, it stretches to cover the entire reel as an expanded wild. That means all five positions on that reel become wild for that spin result.

Expanded wilds are the key to big hits because they can combine with the reel multiplier system. Each reel has its own multiplier value, and when that reel shows an expanded wild, the multiplier for that reel is applied to all winning lines that use that reel. The way those multipliers grow is handled by the Fireworks feature.

Fireworks Respins and reel multipliers

Firework symbols are the engine of the game. They can land in both the base game and the bonus round, and every time at least one Firework lands, it triggers Fireworks Respins. When this happens, the current spin does not end right away. Instead, the reels keep spinning as long as new Firework symbols continue to appear. The moment you get a respin with no Firework, the feature stops.

Each reel has its own multiplier value shown above it. Firework symbols change those reel multipliers in two main ways:

• Additive Fireworks add a flat amount to the relevant multiplier, usually between plus 2 and plus 5. If it lands on a single reel, only that reel’s multiplier goes up by that amount.
• Multiplicative Fireworks multiply the current multiplier by a factor, usually between times 2 and times 5. Again, if it is on a single reel, it only affects that one.

There are also multireel Fireworks. These do not just target one position. Instead, they apply the same additive or multiplicative change to all reel multipliers at once. So a multireel plus 3 would add 3 to every reel, and a multireel times 2 would double all reel multipliers in a single hit.

These reel multipliers do not do anything on their own. They matter when an expanded wild covers a reel. In that case, the multiplier for that reel is applied to the line wins that pass through it. In the base game there is an important catch. Whenever an expanded wild is used in a win, the multiplier for that reel is reset down to times 1 after the win is paid. That keeps the base game from snowballing too hard and makes you work to rebuild multipliers with more Fireworks.

Burning Sky bonus round

The main bonus is called Burning Sky. To trigger it, you need to land 3 scatter symbols in the base game on the same spin. When that happens, you move into a special mode that uses the same 5 by 5 layout and the same Fireworks and expanding wild mechanics, but with some big differences.

First, you start the bonus with 3 lives. A life is basically a spin allowance. Every time you get a spin that does not land any Firework symbol, you lose one life. When you hit a Firework, your life count is reset back up to 3. This means the round keeps going as long as you keep seeing Fireworks. Only when you get three dead spins in a row without any Fireworks does the bonus end.

The second big change is how reel multipliers behave. In Burning Sky, the reel multipliers are persistent. That means they do not reset back to times 1 after an expanded wild is used in a win. Instead, every Firework keeps building them higher and they stay at their new values for the rest of the bonus. They can climb all the way up to times 999 on each reel if you get enough boosts.

This is where the game can go crazy. With several reels holding large multipliers and expanded wilds landing more often, a single spin can connect huge lines across multiple boosted reels. Wild symbols also appear more frequently during Burning Sky compared to the base game, which makes it easier to actually use those big multipliers. On the other hand, scatters do not appear at all during the bonus, so you cannot retrigger it from inside. Once your three lives are used up without more Fireworks, the feature is over and your total win is paid out.

Bonus buys and FeatureSpins

If you do not want to wait for the bonus to land naturally, Mirage City offers two paid options where allowed by the casino.

• BonusHunt FeatureSpins cost 3 times your normal bet. When you activate this mode, the base game still plays as usual, but the chance of landing scatters is boosted to about five times the normal rate. You are basically paying extra per spin for a much higher shot at triggering Burning Sky, but you are not guaranteed to get it on any given spin.
• Burning Sky buy costs 100 times your bet. This option skips the base game and takes you straight into the Burning Sky bonus round on the next spin. You start with the standard 3 lives and reel multipliers at their default values, and then play the feature as normal.

These buys do not change how the features work once they start. They just change how you get into them and how much you pay up front for the chance at a big hit.

RTP, volatility and win potential

At its top setting, Mirage City runs at 96.31 percent return to player. The game is described as extreme in volatility, which lines up with how it behaves. Most base game spins will be quiet, with small line wins and the odd Fireworks sequence that builds a reel or two. The real money is in the bonus, where persistent multipliers and extra wilds can line up for very swingy results. The biggest wins will almost always come from Burning Sky runs where Fireworks keep resetting your lives and pushing multipliers toward the higher end of the scale.
