Robotnik Online Slot Features Versatile Wild Symbols with Wild Win Enhancers
Robotnik is a 5-reel, outerspace-themed online video slot created by Yggdrasil Gaming. The game title refers to an astromech type of robot with a mission to collect rock samples from other planets. In this slot game, Yggdrasil showcases the unique rocks collected by Robotnik, using them as reel icons that can appear as matching symbols in any of the game's 40 paylines.

The rocks are divided into two sets. The raw unpolished specimen represent the lesser paying symbols with equivalent coin payouts of up to 125 for every 5-of-a-kind matched symbols. The polished rocks presented as clusters of multi-faceted gemstones are the high-paying symbols, paying as many as 200 up to 500 coin rewards for five-of-a-kind payline combos.
The rewards could be greater as the game has a versatile Wild Symbol. It could emerge as a Wild with Sticky attribute, a random x3 Win-Multiplier, or as Stacked Wilds; as well as trigger bet-free re-spins by simply emerging as part of paid spin outcomes. Moreover, the featured Robotnik character appears randomly to transform one or more regular symbols into Extra Wilds, including the x3 Wild Symbols.
About the Robotnik Sticky Wild Symbol and Re-Spin Feature
This Yggdrasil online slot does not have a free-spins round but offers re-spins that could go on and on, for as long as Wild Symbols appear as outcomes of a paid spin. In any instance that a Wild Symbol appears across the screen, the slot reel automatically launches a free spin.
During the re-spin, all Wild Symbols stick to the screen, therefore increasing slot players' chances of hitting payline wins. Robotnik slot players have optimised chances of landing on Big Wins, if more Wilds continue to appear during each and every re-spin. Wild Symbols, after all, can be used as substitutes for regular icons in order to complete the required number of matched symbols that form payline-wins. More so, if they appear in multiples and as Stacked Wilds that fill-up an entire reel.
Robotnik Online Slot Betting Options
Bet amount placed per spin in this Robotnik online slot covers for all 40 paylines. Players have the option to place any coin value, ranging from 0.01 to 0.50 on every payline. The lowest amount of bet possible for each spin is 0.40 (0.01 x 40 paylines), while the highest bet amount allowed is (0.50 x 40 paylines).
Slot players should consider that all coin prizes received for payline wins are multiplied by the coin value staked on a payline. A 100-coin reward is equivalent to 1.00 if the bet staked per line 0.01 with a total bet per spin of 0.40. If the amount staked per payline is 0.50, with a total bet per spin of 20.00, a 100-coin reward will have an equivalent cash value of 50.00.
Denoting that regardless of the amount staked per payline, the rate of return per payline win is the same: 1.00/0.40 = 2.50 vs. 50.00/20.00 = 2.50.
