Mars Casino they are part of SoftSwiss N. V. Casinos as I saw just now they have something in common with casinos I really dont like. Maybe 2 casinos of all this group has good ratings as for the rest of them cant say the same. They were established 2016 so not so new I guess and as I mentioned I really dont like the fact, casinos having unresolved complaints.

I do know they have very weird and unusual for me, verifying of account rules but I guess if we follow those rules of theirs everything will be ok? You all know whats my opinion and I believe many players has the same about Curacao licence casinos. I am not saying every casino with the same licence is the same but we all know to expect if some problem appears, one big nothing. . .

Mars Casino even knowing that they own Curacao licence I still wanted to give them a go, read their T&C and must say a lot of restrictions of the games even some contribute very small percentage when it comes to wagering a bonus. But luckily my game wasn't at that list, so I decided to make deposit and take their welcome bonus.

Made 20 euros deposit took their 100% match bonus which follows the wagering of X 40 as I mentioned before not so bad when it comes to wagering and of course 50 free spins on Starburst. Why divide those 50 free spins on Starburst, its not some game it could give me some extra value of it. Well as I said my time there was not something I could brag, because my bonus went so easily, I played for a half an hour and that was it, another zero on my balance.

The next few days had those free spins on Starburst but got very tiny wins so I couldn't play anything then waste those wins on the same game. They might be decent casino but really dont had any withdraw and depositing only once there not much I can say.

I took me many months in hesitation before finally signing up at this Mars Casino, and I finally found out why it was so. The Welcome package for new players was nothing special, just the usual 100% deposit bonus plus 50 free spins on Starburst spread over 2 days. Why need to spread it out over 2 days, I simply cannot reason out! 50 free spins on Starburst is equivalent to 20 free spins on any 25-paylines game, and this need to be played over 2 damn lousy days? Sheesh! I will never like or appreciate any casino's offer of free spins spread over a number of days. For me, it's all in one go, or not at all. Why? Because I would usually forget to claim them over the next few days and end up missing them altogether! Perhaps this is what any casino expects most players to do, so they 'win' indirectly from all the missed free spins. A damn lousy deal if you ask me!

After making my first deposit and getting that 100% bonus money, I looked for a preferred game to play on, but found none! Why? Most of NetEnt's popular games, like Dead Or Alive and Creature From The Black Lagoon, are restricted, or have a reduced wagering contribution. Then I thought I would give NetEnt's latest game, Butterfly Staxx, a go, because some players did have a good time playing them. Well, this game wasn't even in the games list. Why? Beats me! Looks like the Mars people are indeed behind time, as far as I could see, or imagine. That sucks! The only game that I could play on was BetSoft's Fruit Zen. Not a good game to play on, but there wasn't any other game that I had wanted to play. None were my favourites, and I'm not the kind of player who would simply play on any game, or one who would simply waste away my money on any game. No sirree, that's never me!

As for the game Fruit Zen, it hasn't been playing good at all for many months, and it has never played as good as when it was newly released. I know this because it was my favourite game at one time, it was paying more regularly than Starburst could, and I had even won over $3000 on Fruit Zen, for which I could never win from Starburst. Then one day, Fruit Zen got 'upgraded', and it went downhill all the way thereafter. It has never been good ever since. My latest play on it was no exception. It played miserably, as expected. I managed to get once, only once, 3 Wild Reels on the reels, but no high paying symbol appeared on reels 1 or 5, so that only paid me a lousy win of less than 50x my bet amount. What the argh! Needless to say, I then lost all of my deposit and bonus money on Fruit Zen alone. Sheesh!


What do I dislike most about Mars Casino? The ridiculous restrictions on so many games! What's the point of taking up a deposit bonus if I cannot play on any game that I want? Simply playing on any other game would be pointless for me, because I wouldn't be able to win on them, unless I do get lucky of course, but that's a long shot! I don't like taking unnecessary chances and I do prefer to always play on games that I am familiar with. With Mars Casino, this is not possible, so leaving me with no other choice but to avoid further plays at the casino. A very disappointing first trip to Mars, if you ask me!
