I think if I was satisfied with the performance of this slot maybe I would have kept my comment about design to myself, but I am not; I have usually felt that games developed by this provider are generally characterized by having a game system fair enough, however, this game not only shows a little low hit average but within its round of free spins I have found an aspect that I have not really liked it.
To expose what was observed during free games, I must first explain the mechanism by which this round is triggered; so, to gain access to a round of free spins, we need to get 3+ symbols of a pink robot located exactly on the same active payline; 3, 4 or 5 of these symbols give us 5, 10 or 15 free spins, in any case, I never could get more than 5 free games, but that's not the issue that concerns me.
What really bothers me during the round of free games is that pink robots appear just as they do during the base game, but at this stage of the game, these symbols have absolutely no function, except perhaps to sabotage formation of regular lines during it; so, these pink robots do not re-trigger the free spins round even when they appear on the same active payline, and even do not generate any payout for doing so; then why do they appear during this round? I do not know that, and honestly, I think this is not an insignificant matter since spaces occupied by these symbols may well be occupied by other symbols that generate payouts when matching on a line.
As you can imagine, my balance in this video slot always aimed and went to decline, as in free fall and without truce.
Several of the games belonging to this company are included in my list of favorites, but very likely “Roboslots” will not be one of them essentially due to the weaknesses indicated above and, in general, because of its poor potential.
