How do you trigger the bonus in Grand City Heist?

Coloured cash stacks that land in the base game fill the feature of the same colour above the reels. When Extra, Multi or Double is fully filled, the Bonus Game starts with 3 respins, or 4 with Extra.

Can you buy the bonus in Grand City Heist?

No. The demo we played had no bonus buy option, so the coin respin round can only be triggered by filling a feature meter.

What is the RTP of Grand City Heist?

The standard rules list 95.50%. A 94.00% version of the rules also exists, and the demo loaded a 94% profile, so the figure can vary by casino.

How much are the jackpots worth?

Mini pays 15x the bet, Minor 30x, Major 100x and Grand 1,000x. Mini, Minor and Major come from gold bars in the bonus round. The Grand needs all 15 positions of one field filled with coins.

What does the Double feature do?

It adds a second, independent game field with its own respin counter. The stacks that triggered the round are copied onto both fields at the start.

How many paylines does Grand City Heist have?

There are 5 fixed award lines on a 5x3 grid, and wins pay left to right from the first reel.

By the CasinoDemo editorial team · Updated 2026-11-09 · How we review

Grand City Heist is an Onlyplay slot with a neon crime-movie look: a 5x3 grid, just 5 paylines and a hold-and-respin bonus that you build up from the base game. Three crew members sit above the reels, and each one powers a different upgrade for the bonus: Extra, Multi or Double.

We played the demo at a 1.00 EUR bet, read the in-game paytable and the provider's full rules, and ran 200 autoplay spins chasing the bonus. There is no bonus buy, so the respin round has to be earned, and in our session it never came. Everything below comes from the rules and from what we saw on screen.

How Grand City Heist works

The game uses 3 rows and 5 reels with 5 fixed award lines: the three horizontal rows plus a V and an inverted V. Wins pay left to right from the first reel, symbols must sit next to each other on the line, and only the highest combination on each line is paid. Every combination needs at least 3 matching symbols.

The paytable is short. The green-shirted crew member is the top regular symbol at 40x the bet for 5, 10x for 4 and 2x for 3. The other three characters pay 25x, 5x and 1x. The four low symbols (ring, purple gem, brick phone and revolver) each pay 10x, 2x and 1x. Those values are multiples of the total bet, which is why a 3-of-a-kind on a single line often just returns your stake.

Wilds and cash stacks

The golden skull Wild substitutes for every regular symbol but not for any coin or cash stack symbol. It also pays on its own: 50x for 5, 15x for 4 and 3x for 3. The Wild does not appear during the bonus round.

The cash stacks (called Coloured Coin symbols in the rules) are the key to the game. Each carries a value based on your bet, but in the base game that value is not paid. Instead, a stack fills the bonus feature of its own colour above the reels: purple for Extra, green for Multi and red for Double, going by the paytable. At our 1.00 EUR bet we saw stacks marked 1.00, 2.00, 3.00, 5.00 and 8.00 land in normal spins.

The bonus game: coin respins

When one of the three features is fully filled, the Bonus Game starts. Every cash stack on the reels at that moment stays in place as a Bonus Coin with its value unchanged, and you get 3 respins. From then on only Bonus Coins and Jackpot Coins can land. Each new symbol sticks and resets the counter to 3. The round ends when you run out of respins, and all wins are based on the bet of the spin that triggered it.

New Bonus Coins are worth 1x, 2x, 3x, 5x, 8x or 10x the bet. More than one feature can fill on the same spin, and then all of those upgrades apply together. Collecting extra stacks beyond a full meter strengthens the bonus but does not give you a second round.

Extra, Multi and Double explained

Extra adds one respin, so the round starts with 4 respins and resets to 4 every time a symbol lands. That sounds small, but in a hold-and-respin game an extra life per reset adds up.

Multi places random multipliers on reel positions. If a coin lands on one of those spots, its value is multiplied. The paytable illustrates it with an x4 on a 30.00 stack.

Double adds a second game field. The two fields run independently, each with its own respin counter, and the stacks that triggered the round are copied onto both. Since the Grand jackpot is counted per field, Double effectively gives you two shots at filling a grid.

We think Double is the one to hope for, but the rules give no odds for any of them, so treat that as an opinion.

Jackpots

Four fixed jackpots can only be won in the bonus round. Mini, Minor and Major are gold bars that drop at random during the respins and pay 15x, 30x and 100x the bet. The Grand pays 1,000x the bet and is won by filling all 15 positions of one game field with coins. At a 1.00 EUR bet the meters on the left read 15.00, 30.00, 100.00 and 1,000.00. Jackpot wins are paid when the bonus round ends.

What happened in our demo session

There is no bonus buy, so we turned on quick spin and ran 200 autoplay spins at 1.00 EUR. The bonus did not trigger once in those 200 spins. Plenty of cash stacks landed, but none of the three meters filled.

Base game wins were mostly small line hits of 1.00 to 3.00 EUR. The best we saw was a Super Win of 40.00 EUR, 40x the bet, from a screen with several Wilds. Our balance went from 10,000.00 to 9,955.00 EUR over the session. That is one short session, not an average, and the bonus round, where the jackpots live, carries a lot of this game's value.

RTP, max win and bets

The standard rules list an RTP of 95.50% for the main and bonus game combined. Onlyplay also publishes a 94.00% version of the same rules, and the demo we played loaded a 94% certification profile, so check the rules at your casino. The rules say total wins per round are capped by a Max Win shown in a Limits section, but the demo did not display that figure, so we won't guess one. The largest fixed prize is the 1,000x Grand jackpot.

The demo offered bets of 0.50, 1, 2, 5, 10, 20 and 40 EUR. Autoplay runs 10 to 1,000 spins or unlimited, and stops when the bonus game starts.

Our verdict

Grand City Heist is simple on the surface and lives or dies by its coin respin round. The three upgrades give the bonus real variety, and Double plus the 15-coin Grand is a strong combination on paper. The downside is that there is no buy and the base game pays modestly on just 5 lines, so dry spells happen: we went 200 spins without a bonus. Try the demo first and see if the pace suits you.
