Space Gems. Rockblocks is a slot produced by Mascot Gaming studio. It was released in the middle of December 2024. Despite very little bonus functionality, I enjoyed playing it. The slot has a large 6x6 field, payout mechanics with no lines for groups of symbols, 2 unusual symbols. There are no free spins and the usual Wild, but there are cascades, risk round and random additional multipliers. The win limit is small and is x750.

Start getting to know the slot in demo mode - it's free and doesn't require registration. We've added the demo to the beginning of the review so you don't have to search for it and go to other sites.
In the demo mode there are no restrictions on slot functionality, number of spins or playing time. Therefore, you can study the rules and understand whether you want to risk real money.
You can choose a casino to play this slot for money from the ready-made Casinoz list. All of the sites that are added to it have the Space Gems. Rockblocks in the catalog. That way it won't have to be searched through different casinos.
The Space Gems. Rockblocks is a slot with a large 6x6 field and with no line payouts. It pays 5+ identical symbols if they appear next to each other, touching at least one side (except for the corners, neighboring diagonally doesn't count). There is also an Astronaut symbol that pays on any cells. After any win, a cascade is triggered and the paid symbols disappear from the field.
You can set a wager of 0.20, 0.40, 1.00, 2.00, 5.00, 10.00, 20.00 or 50.00. The winnings cannot exceed x750 of the bet. The restriction applies to a series of cascades or a risk round.
These symbols differ from simple symbols in that they have special properties:
Astronaut. 5+ such symbols turn into coin symbols with random multipliers and pay. This happens on any cells, no touching is needed for these symbols to pay out.
UFO. When it appears on the field, it activates a random additional multiplier. If UFO falls not at the beginning of a series of cascades, but later (for example, after 3 winning combinations) - its multiplier will still apply to the payout of the entire series. That is, to the combinations that won before it appeared.
The developers have added only 2 bonus features to the slot:
Risk Game. This is a wheel of fortune with 3 rings. On it you can catch a multiplier from x2 to x5. The gambler himself decides whether to launch the risk round or not. After each win, the Risk button appears next to the manual start button. You can start the next spin, and then it will disappear. You can disable the appearance of the Risk button in the settings.
Rockfall Feature. All symbols (including Astronaut) that gave a payout are removed from the field. New ones fall in their place. The UFO symbol is also removed from the field after it activates an additional multiplier. This happens even if there is no winning combination on the field, in which case only the UFO is removed.
The slot is set to have these payoff parameters:
RTP is 94.90% (below average).
The volatility is low, meaning there are plenty of gains, but most of them are small.
The payout frequency is about 3-4 wins in every 10 spins. Repeat wins after triggering cascades also fall out often, because the field is removed from the minimum of 5 symbols.
All strategies that are published anywhere, or that can be invented by the player himself - in slots do not work. Apply them impossible, because the result of rotating the reels is always random. The choice of 1 combination occurs from thousands of possible options. No analysis will not help to guess what symbols will fall next time.
That is why it is better not to start playing for those who dream of finding a strategy for a guaranteed game in the plus - there is no such thing.
There is nothing superfluous in the slot interface - everything is centered at the bottom, below the field. The only element that appears elsewhere is the size of the multiplier that activates the UFO symbol. It is shown in the bottom right corner next to the field. On the bottom left there are 2 buttons: menu and bet selection. The menu hides the pay table, settings and a page with information and rules. There are few settings: you can turn on/off music, game sounds, full screen mode and risk round offer. In the center at the bottom (or right when playing on mobile devices in landscape orientation) are the start buttons (manual and automatic) and a button to speed up (or slow down) the reels. The balance is shown on the right and the payout you just received is highlighted. I did a trial session and from my experience I advise:
Play the demo to understand the principle of winning combinations, cascades, and the UFO and Astronaut symbols.
To play for money, lower your bet so your deposit is enough for more spins.
Set the settings for automatic spins. This way you don't have to click on the start manually every time, you can only look at what symbols fall out. You can stop the auto spins by pressing the button or set the conditions: number of spins, winnings, balance decreasing or increasing above a predetermined level.
Android and iOS devices will run the mobile version for easy play. The main difference from the PC one is in the interface. All buttons and text font are enlarged. The button layout automatically changes when you rotate the gadget from landscape orientation to portrait orientation and back again. The design is adaptive, so both on a small phone and a large tablet the slot will look right and be displayed in its entirety.
Casinoz editorial conclusion: not the most interesting slot from this provider, but I didn't want to close it after a few spins either. Cascading payouts and unusual symbols make the game more interesting.
The rate of return to the player is 94.90%.
The online slot offers 6 reels in 6 rows.
Players can bet a maximum of 50 euros.
