Wild Booster review
Wild Booster is a 3x5, 20-line Pragmatic Play slot with classic symbols and a very active wild. Any spin with a wild can trigger a random multiplier of up to 100x on the wins that include it. The free spins add a decision: before the round starts you pick between a Mega Boost mode and an Ultra Boost mode, each with a different multiplier ladder. The maximum win is capped at 5,000x the bet.
The wild and the Wild Boost
The wild lands on all reels and replaces every symbol except the scatter. Its main job is the Wild Boost. On any spin where at least one wild hits, there is a chance that the feature triggers and picks a random multiplier. The possible values are 2, 3, 4, 5, 6, 8, 10, 12, 15, 25, 50 or 100 times. The multiplier is applied to every winning combination that contains a wild, not to the whole spin.
That last point matters. A big multiplier on a small line win stays small, so the feature pays best when the wild sits on a line with high-value symbols.
Super Boost free spins: Mega or Ultra
Three or more scatters anywhere start the Super Boost round. Before it begins, you choose one of two options. Both are progressive: the round opens with a Wild Boost multiplier that can rise three times as scatters are collected. The number of scatters that triggered the round counts as the first ones collected.
Collected scatters raise the multiplier on every fifth scatter. Each new level brings 5 more free spins, and the rules add that retriggered spins are played after the previous batch has ended.
Mega Boost
Starts with 5 free spins and a x2 Wild Boost multiplier. Fewer scatters are on the reels, so the multiplier is harder to raise. Every fifth scatter lifts it, first to x5, then x10 and finally x100.
Ultra Boost
Starts with 5 free spins and a x3 multiplier. More scatters are on the reels, and the chance to raise the multiplier is higher. Every fifth scatter lifts it to x6, then x12 and finally x50.
Choosing between the two
Mega Boost has the higher top (100x) but the slower route, while Ultra Boost reaches its levels more often but stops at 50x. The rules do not state the odds of either, so the choice is between a longer shot and a steadier climb. The demo is a safe place to compare them.
Buying the round and what it costs
The Super Boost round, with both options, can be bought from the base game for 75x the current total bet. The number of scatters that hit on a purchase is random, from 3 to 5. At a $1 bet that is $75, and the price grows in proportion to the stake.
The RTP is 96.47%, and the house edge is 3.53%. Per $1,000 wagered the average loss is $35.30. A 100-spin session costs $0.71 at a $0.20 bet, $3.53 at $1 and $17.65 at $5. The maximum win is 5,000x the bet: $1,000 at $0.20, $5,000 at $1 and $25,000 at $5. No volatility label is published.
Similar 2021 and 2022 releases

Pros
- Wild Boost multipliers from 2x to 100x on any spin with a wild
- A choice of two free spins modes with different ladders
- Buy option at 75x the bet
- Free official demo available
Cons
- Wild Boost applies only to wins that include a wild
- The odds of each free spins mode are not published
- No volatility label is published
Verdict
Wild Booster is an easy-to-read line slot whose features revolve around the wild. A 96.47% RTP gives a 3.53% house edge, and the 5,000x cap is moderate. The Mega or Ultra choice is the most interesting part, but the pack gives no odds for it, so the free demo is the best way to see which suits you before choosing a stake.
