Diamond Explosion 7s SE — Cazeus
The two letters at the end of the name are not decoration. SE stands for Special Edition, and it identifies the RubyPlay build of Diamond Explosion 7s that ships with a Buy Feature — the option to pay for immediate entry to a bonus round rather than waiting for it to arrive. Everything else is the same machine, which makes this one of the rare cases where the version label genuinely changes how the game is played.
CazeusWhat Diamond Explosion 7s SE actually is
RubyPlay builds this in the American fruit-machine register: sevens, bars, diamonds and a lot of chrome, laid out on a five-reel, three-row field with 50 fixed paylines. Fixed means the bet always covers all fifty; there is no line selector to economise with.
The published return is 96.37% and volatility is rated medium to high, but the number that describes the feel of the game is the hit frequency: 47.96%. Almost every second spin returns something. That is a very particular rhythm — the reels are rarely silent, and it takes deliberate attention to notice that a large share of those returns are smaller than the stake that produced them. A busy screen is not the same thing as a rising balance.

Three bonus routes, not one
The feature set is unusually layered for a classic-looking slot. The standard route is scatters: land three and the game awards eight Free Games, and during each of those spins one randomly chosen reel is filled entirely with wilds and diamonds. Because the reel is selected fresh each spin, the round has a built-in swing — a wild reel in the middle of the field is worth far more on a 50-line layout than one at the edge.
The second route is the Explosion Free Games, opened by six or more prize symbols appearing together. This is a separate round with its own trigger, so a screen that fails to produce three scatters can still convert into a bonus through prize symbols alone.
The third is Jackpot Pick Deluxe, a picking round that awards one of four fixed tiers: Mini, Minor, Major or Grand. Four tiers means the outcome distribution inside the round is itself uneven — most visits end at the bottom of the ladder, and the Grand exists to justify the 8,047x ceiling rather than to be a realistic session goal.
Bets, bankroll in euros and the arithmetic of buying in
RubyPlay leaves the stake range to the operator, so the bet selector inside the game is the authority. The Buy Feature price, though, is fixed as a ratio: 50x the current bet. That ratio is what makes the decision straightforward to model. Buying at a 0.20 stake costs 10 EUR — exactly what fifty ordinary spins at that stake would cost. So the honest question is not whether the bonus is worth 10 EUR, but whether one guaranteed bonus round is worth more to you than fifty spins that might produce one anyway plus all the base-game returns along the way.
In bankroll terms: a 20 EUR deposit at 0.40 per spin is 50 spins, or alternatively two feature purchases at a 0.20 stake with nothing left over. A 50 EUR deposit at 0.50 per spin gives 100 spins, and at 0.20 it gives 250 — the wider sample, and the one that lets the 47.96% hit frequency actually express itself. Feature buys are the fastest way to convert a bankroll into a small number of high-variance outcomes, which is a legitimate choice as long as it is made on purpose.
Demo mode, wagering and what nobody here underwrites
The demo is more useful on an SE build than on most games, because it lets you press the buy button at play-money prices and see what a purchased round typically returns before spending real euros on the same decision. What the demo cannot show is anything financial: no euro balance, no cashier, no wagering counter, and no indication of whether a promotion permits feature purchases at all.
That is a live question here. Slots normally contribute in full toward turnover, but the contribution table belongs to the promotion in the cashier rather than to the game, and buy features are among the most commonly restricted actions while bonus funds are active. As arithmetic only: 35x on a 60 EUR bonus is 2,100 EUR of accumulated bets. Confirm what is allowed in the wagering rules and the bonus terms before pressing buy with bonus money.
Worth being blunt about the regulatory side as well. No Slovenian concession covers Cazeus, and none could be issued to it — the concession regime is limited to companies established in Slovenia, in practice Loterija Slovenije and the Casino Portorož / HIT group. FURS supervises the market and blocks unlicensed domains, but it is not a dispute body for players of this platform. Applied here: the 96.37% return, the 47.96% hit frequency and the 50x buy price are RubyPlay figures, verified by the studio testing chain and by nobody in Slovenia. The only figure you can independently confirm is the one displayed in the information panel of the exact copy running in the lobby.
