How to play

Though the slot is packed with additional options, its main game is pretty plain, and the general rules won’t make players confused. The explained rules are here:

  1. Create an account at a casino or log in
  2. Read the terms of available bonuses and activate them
  3. Open the slot and select your stake between €0.20–€20
  4. Rotate the reels once or during a long session

The 20 lines the game features are an unchangeable parameter. The whopping 4 bonus symbols provide truly wide opportunities for users.

Diamond Heist Hold & Win RTP and Volatility

8 
The parameters of a 96% RTP and med-high volatility are actually normal for an average Hold & Win slot.
If you don’t know how to divide your stakes, keep in mind the slot’s variance. It’s med-high, which is more about a risky game, though not a total high roller parameter. That’s why you have to count on a bit of longer sessions and divide the amount you have into at least 10 to 20 spins. And as for the RTP, a 96% score is a reliable parameter.

Theme

8.2 
Criminals are here and there as well as the riches on the reels. The theme allows gamblers to feel like real thieves and, more importantly, earn something when the crimes are successful. The music is tricky and the sirens sound when police symbols take place. From time to time, a horror theme is displayed during the pause.
Theme

This game is packed with luxury items on the reels and equipment of criminals to own these riches. That’s why there are 10 symbols and the whopping 4 bonus ones.

All 10 standard symbols are paid for when there are 3 to 5 of them. They land on any of 20 paylines and when several lines bring winnings at once, each of them is paid. The slot has a record number of bonus symbols, and it's great for those who are searching for bonus features. While it may be challenging for those who want to form standard combinations during the base game.
