Reflex Gaming's Time Machine seems to be underdeveloped in terms of the whole time traveling aspect, especially when compared to, for example, Betsoft's Miles Bellhouse And The Gears Of Time slot game. Although you get a decent retro steampunk visual presentation, there are some time-related and strange machines on display on the 5x3 grid of the starting grid, so it's not all bad. There is more of a grid expansion journey than it is a time travel journey really, and things are kept quite simple throughout the entire journey.

There are a number of ways to win in the base game, with the most common being the Pay Rise Reels mechanic, which expands the grid by +1 row for consecutive respin wins. It is not very common for the grid to be maxed out with four rows, since this is how you are able to trigger the bonus round when it happens. It is good news to know that the grid in the feature is maxed out with 16,807 win ways, giving you a fair chance of fitting in the 27,471x potential (which is extremely solid for a low volatility release).

In this game, the premium symbols pay between 3 and 10 times your stake if you achieve 5 of a kind, and the Wild symbol acts as a substitution for all regular pay symbols in order to help you complete winning combinations. Although the wild does not hold any value of its own in this game, the Pay Rise Reels are without a doubt the game's defining feature that sets it apart from the others.

If you land a winning combo, the Pay Rise mechanic will trigger, and this will expand the grid with an additional row whenever you land another winning combo. The expanded grid is also rewarded with a respin, and you can expand the grid with up to seven rows in total if you land consecutive wins on the respins that you receive. The amount of win ways increases from 243 to 16,807 at the most, and everything resets on a spin that does not result in a win.

It is when you have maxed out the grid with 7 rows that the Bonus Round will trigger, and you will then be given 7 free spins. As long as you land a +1 symbol during the feature, you will receive an extra spin, and the bonus round grid will always be set up with 7 rows and 16,807 ways to win.

We've had a decent enough time testing this latest installment of Reflex Gaming, and as usual, we've whipped together a brief and edited highlights video for you to check out. The video below shows you only the most interesting moments from our 200-spin test session, and you can start watching right away by simply clicking on the play button below to get started.

Time Machine from Reflex reminds us of Wild Streak Gaming's Amazing Money Machine in terms of its steampunk retro visuals, but it is on the simpler side both in terms of visuals and features compared to Amazing Money Machine. As a result of the defining Pay Rise Reels mechanic, you will come across a lot of "premature" grid reset moments with a somewhat annoying pause between hitting the spin button again and the grid resetting, which might induce a certain amount of fatigue in some players. Our experience was that it worked for us at least.

Yes, you will be able to crack the solid 27,471x potential from a single spin if there are 16,807 ways to win, and even less than that. The probability of that happening is, of course, another question, and there is no information provided about the probability of a maximum win. Obviously, when the grid is always maxed out in the bonus round, your chances increase, but it would have been nice if there had been some time-travel related extras included as well. The overall effort is mediocre, even though the math model used is somewhat unusual.
