Monopoly: Big Event is a slot machine from the UK based slot provider Barcrest. This is one of several slot machines that are based on the popular board game Monopoly, another example is Super Monopoly Money from WMS. There are two different game plays to choose from on this slot machine. There's a normal base game, where you spin one spin per bet, and there's a Big Bet feature where you buy 5 consecutive spins for €20 or €30 per game round. As on many of the other Barcrest games, the Big Bet games increase the possibility to trigger the combined bonus game and free spin feature. It's difficult to calculate the exact maximal potential win for this slot machine since it features sticky wild symbols during the feature, but the potential is at the higher end. The payout percentage of this game is a bit special. If you chose to play the base game, the RTP is 96%, but if you play the Big Bets it increases to up to 99%.

Game features

This game can be played with a normal bet, or a Big Bet. The different features will vary a bit depending on what kind of bet you place. Some of the features are only available during the Big Bet feature. I'll try to explain it during the descriptions below.

Monopoly: Big Event has wild symbols on all the reels during the base game. These symbols substitute for all other symbols except the Big Event bonus symbols. There are several other ways to get wild symbols to appear in this game as well, and I will describe them in the below section. There is a combined bonus game and free spin feature on this slot machine. The bonus game is a pick bonus, and it will determine what kind of free spin feature and wild symbols you get during the free spins. There is also a Big Bet feature that increase the payout percentage from 96.00% to a generous 99.00%.

Big Bet feature: There are two different Big Bets that can be made on Monopoly: Big Event, and all Big Bet spins are paid according to the bet size of €1.00 per spin. A €20 bet will buy you 5 consecutive spins where a progressive win multiplier is in play. The first spin will have a win multiplier of x1, while each of the next spins will increase the total multiplier by +x1 per spin. The 5th spin will then have a multiplier of x5. The current multiplier value can be seen on the right hand side of the game. A €30 bet will also buy you 5 consecutive spins, but here there are 3 different options that can apply to the spins. If the €30 bet is bought, a lucky wheel with 3 different features are shown on the screen. A spin will be made, and whatever feature you land on is what you get for the next 5 spins.

The options are: A blue progressive multiplier, which is the same as you get in the €20 bet. You can also win a green persisting wilds feature. This will make all Big Event symbols wild and sticky during the 5 spins. The last option is the yellow epic spins. If you land on this feature, all 5 spins will have a x5 multiplier applied to all wins. The Big Bets feature a way higher frequency of the combined bonus game and free spin feature, and it's by far easiest to win it from the green persisting wilds feature, where the bonus symbols turn into wilds and sticks to the screen. A combination 3 of them will activate the bonus.

Bonus game / Free spins: The free spins can be triggered in a couple of ways. During the base game, a combination of Big Event symbols has to land on reel 1, 3 and 5 for the bonus to trigger. During the Big Bet's the same combination is needed, but for the green persisting wild feature it's enough to get 3 Big Event symbols anywhere on reel 1, 3 and 5. The 5th reel has stacked Big Event symbols during all the different bet sizes. Except for the persisting wild feature, you will always need a bonus symbol on reel 1 and 3, and then you can get 1, 2 or 3 additional symbols on the 5th reel. The number of symbols that trigger the bonus will reflect the bonus features.

The bonus starts off with a pick bonus game. There are 15 community chests on the left side of the game and 9 chance cards on the right side of the game. The community chests can contain free spins or guaranteed wins, while the chance cards contain dices, houses or hotels. You start off by picking a community chest by clicking on it, then it's time to pick a chance card. This process will continue alternately until 3 dices, houses or hotels are found. The longer you continue before a match is found behind the chance cards, the larger amount of free spins and win spins can be found behind the community chests.

If the bonus was triggered with 4 or 5 bonus symbols a sneak peek is rewarded. 4 symbols will show you where the green houses are hidden, while 5 symbols will show you where the red hotels are hidden. There is an optimal strategy for this game, and I would suggest that you read the below section before you proceed. All of the free spin options has an In Jail symbol that can appear during the spins, for each time this symbol appear, one of the low paying symbols will be put in jail, and then those symbols will be removed from the reels for the remaining spins. 10-J-Q-K-A will all be removed in the shown order for each In Jail symbol that appears.

If you find 3 dices, the amount of found free spins will start with no additional features. 3 green houses will start the free spins with a dancing and stacked wild symbol. This symbol will jump between the reels for each spin, and guarantees you one wild reel for each spin. 3 red hotels will activate the best free spin feature, a feature where all appearing wild symbols will become sticky for the remaining spins. This means that if you get for example two wilds on the first spin, they will stick to the reels for the rest of the spins.

The guaranteed wins that can be picked during the community chest picks will be shown in the upper right corner of the game during the free spins. For each win you get, you lose one guaranteed win spin. If you have guaranteed win spins left after all free spins have been used, your taken to a different kind of reel set. This is a multiplier wheel that will grant you with one spin per remaining guaranteed win. Each value will multiply you total bet size with between x1 and x50 the stake per spin. For Big Bet's the multipliers will be multiplied with €1.00, as this is the bet size that's in play for each spin during the Big Bets.

Optimal strategy: There's not many slot machine where you can actually influence on the outcome and payout percentage of the game, but at Monopoly: Big Event that's possible. If the bonus game is triggered with 4 or 5 bonus symbols, a sneak peek is awarded. This feature will reveal where the green house symbols, or the red hotel symbols are hidden. 4 symbols show the houses, while 5 symbols show the hotels. The optimal strategy for 4 symbols: Start off by picking 2 of the revealed house symbols, then pick randomly among the other symbols until you get a match. It's never optimal to choose 3 green houses.

The optimal strategy for 5 symbols: Pick 2 of the red hotels before you pick until you have found 2 green houses and 2 dices. Then pick the red hotel. It's not optimal to pick the 3 hotels before you how found two of each of the other symbols. This might sound a bit strange, but the value of getting the extra spins in between the picks is so high, that it's worth risking getting the dices during the picks. The optimal strategy will result in a theoretical payout percentage of 96.00% during the base game and 99.00% during the Big Bets.
