100 Sevens Diamond Treasures: Fill the Chest for a 9,999x Prize

In 100 Sevens Diamond Treasures, Apparat Gaming keeps the fruit machine exactly where you expect it, then builds a vault into the side of it. Five reels with four rows carry 100 paylines of cherries, bells, and flaming sevens, up to 100 free games that can retrigger, and a diamond chest beside the grid holding wins as high as 9,999x the bet.

The base game was strong, with wins arriving every three to six spins and mostly paying between 0.08x and 2x my bet. The 7 tops the regular symbols at 8x for five and pays from just two of a kind, so it turns up more often than anything else. Diamond wilds fill in for everything except the stars, and they rescued enough half-finished lines to keep me level.

Diamond Treasures is a side bet with four levels, and each one costs extra on every spin. I ran levels 2 and 3 for most of my session, and level 2 alone doubles your total bet. 

Diamonds land at random and collect in the chest beside the reels, and once enough pile up, the chest can fire a prize draw. Four reels of digits spin, and the four-digit number they form is your multiplier, which is where 9,999x comes from. Mine never fired in roughly 70 spins, so I turned it off.

Lucky for me, or so I thought, three stars then handed me 10 free games with the 7 promoted to a second wild. I aimed for at least 15, since four stars gets you there and five gets you 100, while more stars inside the round add 10, 15, or 50 on top. 

None of that arrived. The sevens kept the round breathing, but no extra stars came and I left with 8.2x, and after that, I saw no reason to switch the chest back on.

Overall, Apparat gave the fruits and sevens a real boost with up to 100 free games and a chest that can pay four figures, but I saw very little of either. The strongest part of my session was the base game, and that can't carry a slot like this alone.
