Coin Volcano: 3 Oaks' 3x3 coin slot on 1xBet Algeria
Coin Volcano is a 3 Oaks slot played on a 3x3 grid where only the middle row pays. Its base game has no regular symbols at all; every prize is won inside the Bonus Game or the Ultra Bonus Game, through coins, lava multipliers and a ladder of four jackpots.
What is on screen
A glowing red volcano with the COIN VOLCANO logo stands against a purple backdrop, and a green BUY BONUS button sits beneath it. Four jackpot plaques, GRAND, MAJOR, MINOR and MINI, run along the top of the grid, and the middle row is shaded red to mark the win line. Gold coins show either a cash value or a jackpot name. Turbo and autoplay buttons sit beside the large spin button, which reads "Hold for Turbo Spin".
Getting into the bonus
Any three symbols landing on the middle row start the Bonus Game or the Ultra Bonus Game. The Ultra Bonus Game can also be triggered at random during the base game. Meanwhile a Sticky Coin may appear at random and stay on the reels until a bonus begins, worth 5 to 9 times the total bet. Spinning at a different bet clears any Sticky Coins, and having them on the win line does not make a feature round more likely.
Inside the Bonus Game
You get three re-spins, and each new bonus symbol sets the count back to three. Only bonus symbols drop, and all of them stick. The round ends when the re-spins run out or when all nine cells are filled. Along the way:
coins pay 1 to 4 times the total bet, and bonus symbol values range from 1 to 9 times the bet;
Mini, Minor and Major symbols award the matching jackpot;
a Mystery symbol turns into any symbol except the Sticky Coin, while a Mystery Jackpot can only become Mini, Minor or Major, and both open one by one at the end;
Coin Collect grabs every coin and jackpot prize on the reels straight away, then stays in place.
Jackpot ladder
Prize | Pays |
|---|---|
Mini Jackpot | 10x total bet |
Minor Jackpot | 20x total bet |
Major Jackpot | 50x total bet |
Grand Jackpot | 500x total bet, for collecting all 9 symbols |
Volcano Multipliers can fire at random during either bonus: the volcano throws 1 to 9 lava multipliers onto random positions, and repeated hits on one cell raise its value. They apply at the end of the round. Other developers, 3 Oaks among them, appear in the provider directory.
Bonus Shop
The Bonus Game costs 30 times the total bet, the Ultra Bonus Game 75 times, and either one is played at the bet used to buy it. The Ultra version always opens with Volcano Multipliers, and that feature returns more often there.
Demo, dinars and the app
From the slots catalogue, Coin Volcano can be opened free with no real stake. Real-money spins in Algeria are paid from a 1xBet account in dinars (DZD). On iPhone the 1xBet app installs from the App Store alone (setup steps on the iOS app page), and Android uses the APK supplied by the site. Dealer-led tables are found in the live casino.
