100 Blue Star

100 Blue Star Slot Review — AGT Software

AGT Software released 100 Blue Star on 01.07.2022 as a 5-reel, 100-payline machine built around a progressive jackpot rather than a fixed maximum win. Betting runs from 0.1 to 50.0 per spin, and the paytable combines a dense, classic symbol set with expanding and stacked wild mechanics that push toward the jackpot pool instead of a free spins round. AGT Software, the studio behind the release, is based in Riga, Latvia, and has been building its slot catalog since 2019.

Core Gameplay Experience

100 Blue Star runs on a 5-reel, 4-row grid with 100 fixed paylines, which keeps spin rhythm fast and win frequency driven mainly by line hits rather than cluster or Megaways-style grids. The visual theme sticks to a classic fruit-machine cabinet: watermelons, grapes, cherries, lemons, plums, oranges and bells sit alongside stars and black-and-blue sevens, giving the reels the look of a traditional bar-style slot rather than a themed adventure title.

Features and Mechanics

The wild symbol substitutes for other paytable icons and can expand to cover a full reel position when it lands, which is what drives the expanding wilds mechanic listed for this title. Stacked symbols and stacked wilds extend that effect further: when a wild or a high-value icon lands stacked across several positions on a reel, it raises the chance of a full-reel win or an expanded wild triggering on the same spin. Scatter symbols appear across the reels and feed into the game’s bonus mechanics, working alongside the wild set rather than replacing it. A gamble (double-or-nothing) option lets a player risk a line win on a side game after a spin, which is the only way in 100 Blue Star to multiply a single win beyond the base payline result. The progressive jackpot sits apart from these mechanics as the slot’s uncapped prize; AGT Software does not publish a separate fixed-multiplier top win for the base game, so the jackpot is the only open-ended payout in this title. The feature list for 100 Blue Star does not include a free spins round — win potential here comes from the wild mechanics, the gamble feature and the jackpot rather than from bonus spins.

RTP, Volatility and Payout Model

RTP for 100 Blue Star is set at 96.52%, and AGT Software rates the volatility as medium-to-high, meaning payouts cluster less often but can run larger when the stacked and expanding wild features align. A 96.52% RTP sits in the 83rd percentile of the 4,483 slots in our catalog with a published RTP figure, against a catalog median of 96%. High volatility of this kind is shared by 62% of the 4,748 slots in our catalog, so the profile is common rather than unusual, but it still means bankroll should be sized for extended stretches without a line win, with the gamble feature adding further swing on top of each payout. A player working with a small session budget should expect dry spells between the wild-driven hits that make up most of this slot’s return.

Similar AGT Software Slots — Comparison

Across this group of five AGT Software titles, published RTP figures range from 96.49% to 96.52%, with 100 Blue Star matched exactly by 100 Ice Cream on return, while paylines vary more sharply, from 100 up to 256 on Fool’s Day.

Similar Expanding Wild Slots from Other Studios

Of these three titles sharing the expanding wild mechanic, Action Dragons posts the highest RTP at 96.57% and Alaska Fever the lowest at 95.05%, while 100 Blue Star’s 96.52% sits between them, closer to the Action Dragons figure.

How to Play 100 Blue Star Online

Demo mode is the practical way to see how the stacked and expanding wilds behave across the 100-payline grid before any deposit is involved, since the gamble feature and jackpot contribution only become relevant once real bets are placed. AGT Software titles run at five casinos in our catalog, including BirdSpin, SpinLine and 22bet; checking that an operator holds a valid licence and offers the demo version first is the practical starting point before playing 100 Blue Star for money. The wider slots category and the demo catalogue are useful starting points for comparing this title against other jackpot-driven machines before committing a bankroll.

Verdict on 100 Blue Star

100 Blue Star suits a player who wants a classic, fast-paced fruit-machine format with a progressive jackpot chase and enough wild-driven variance to tolerate uneven sessions; the gamble feature adds an optional way to press a win further for those comfortable with that extra risk. It is a weaker fit for a player who wants frequent, steady small payouts or a dedicated free spins bonus round, since neither is part of this title’s feature set — the win path here runs through wilds, the jackpot and the gamble option instead.
