Doctor Winstein is a slot game developed by CT Interactive - this game is inspired by science and research. The main hero of the game is the scientist that wants to invent combat robots that will be able to properly interact with the human brain.

If you’re a fan of CT Interactive or simply played at least one of its games, you’ll probably know that all symbols and design elements are perfectly drawn, and the sound effects are great and, what’s more important, not distracting. Moreover, the blue background seems calming and relaxing.

As we have pointed out, the symbols are perfectly drawn, and we can see that the developers paid meticulous attention to the design part. Even though some symbols are made in simple number shapes, they are greatly complemented with additional lines and patterns. Overall, there are 11 symbols, including both regular with lower or higher values and special ones. Let’s talk more about special symbols.

  • Scatter Symbols. In this slot all paying symbols are considered to be scatters. But only the red button will grant you free spins if you collect 3 of them.
  • Wild Symbols. Wilds substitute for all other symbols but for the red button.
  • Bonus Symbols. The yellow bonus symbol can appear only during free games - it multiplies the winning amount. The multiplying values may be 2x, 3x, 5x, 10x, 15x, and 100x.

Multiplier: x27
A pretty funny, even a little bit crazy slot. The most shocking part is a cascading mechanics. You won’t many cascading slots from CT.
A slot has pretty cheap symbols, but a series of winning cascades can bring decent wins. But, ofc, free spins round is where the most juice due to additional multipliers. The max multiplier is x100.
The slot rends to go on empty streaks. Even 30-40 fully empty spins are not that rare. Watch your balance and plan bankroll for longer sessions.

Winning: €17
Multiplier: x56
The slot looks fine and reels are cascading. Indeed there are a lot of dead spins and average wins in the base game from x2 and up to x8. Slim pickings, right? Anyway the slot is marked as high volatility so my goal was to trigger FS round and check it. I've achieved my goal after maybe 300 spins done. I enjoyed the FS roud as it offers a growing multiplier and 15 is a great number of free spins.
I suppose this slot will like players who reserved some balance for a long spinning
