Slot Theme & Visuals
An erupting volcano with glowing lava cracks stands next to the 4x3 grid, and the palette runs from deep red to orange. Each reel cell carries a molten lava texture, and gold coins show their values in large numerals.
Jackpot coins carry MINI, MINOR and MAJOR labels, while the Mystery Jackpot looks like a cracked lava ball. The logo puts an arrow over the U. In the bonus, a strip of SUPER REEL UP, SUPER MYSTERY UP, SUPER MULTI UP and SUPER COIN UP tiles hangs over the reels.
Active Lines and Sticky Coins
With 1 line only the middle row counts; 3 lines add the top and bottom rows and cost 3x Base Bet. Base Bet equals Total Bet divided by the number of active lines. More lines raise the chance of starting the Bonus Game, which needs 4 Bonus symbols in a row on any active line.
Changing the line count leaves Bonus symbol values and the Bonus Game bet untouched, since the round always plays at Base Bet. At a $1 Base Bet, 3 lines cost $3 per spin.
A Sticky Coin can land at random in the base game and stays on the reels until the Bonus Game starts. There it is worth 5x Base Bet, or $5 at a $1 Base Bet.
Sticky Coins on an active line do not raise the trigger chance. A spin at a different bet or a different number of lines wipes every Sticky Coin from the reels.
Hold and Win Bonus Game
The Coin Up Volcano game plays its bonus at the Base Bet of the triggering spin, and only Bonus symbols land on the reels. Every one of them sticks until the round ends.
Play starts with 3 re-spins. Each new or unlocked Bonus symbol resets the counter to 3, while UP and SUPER UP symbols leave it as it is.
The grid expands to 4x6: the bottom 3 rows are open, and the top 3 rows start locked and open up during the round. The Bonus UP row over the reels is active only here. Re-spins run until the counter reaches zero, and Bonus symbol values plus any Grand and Royal prize add up to the total win.
Mini, Minor and Major Jackpots
Jackpot coins drop at random during the Bonus Game and pay a fixed prize: Mini 10x, Minor 20x and Major 50x Base Bet.
A second route to these three tiers is the Mystery Jackpot symbol, which only ever reveals Mini, Minor or Major. All three prizes are tied to Base Bet.
Grand and Royal Jackpots
Collecting all 12 symbols of any type on the Grand Jackpot reels pays the Grand Jackpot of 500x Base Bet. The Royal Jackpot of 1000x Base Bet needs all 24 symbols of any type, and the 4x6 grid holds exactly 24 cells.
When the 24th symbol lands on the Grand Jackpot reels, both prizes pay for 1500x Base Bet.
Bonus UP Row: UP and SUPER UP Symbols
The row over the reels works only during the Bonus Game. An UP symbol acts on the reel directly under it, and its SUPER version acts on all reels.
- Reel UP / SUPER Reel UP: Reel UP unlocks the bottommost locked cell of its reel; SUPER Reel UP unlocks the bottommost locked cell of each reel.
- Mystery UP / SUPER Mystery UP: these touch Mystery symbols only. Mystery UP turns all active Mystery symbols on its reel into Mystery Jackpots; the SUPER version does it on every reel holding one.
- Multi UP / SUPER Multi UP: a multiplier goes to all symbols on its reel, or on all reels for SUPER. Multipliers stack through the round and apply at the end of the Bonus Game.
- Coin UP / SUPER Coin UP: Coin symbols in opened cells move up a level on its reel, or on all reels for SUPER. A 4x Coin becomes a 5x Sticky Coin, and a Sticky Coin becomes a Mystery Jackpot.
Mystery and Coin Collect Symbols
A Mystery symbol turns into any other symbol except Sticky Coin. A Mystery Jackpot turns only into Mini, Minor or Major. Both types open one by one at the end of the Bonus Game.
Coin Collect gathers every Coin and Jackpot prize on the reels the moment it lands. Multipliers apply to those prizes before the collection, and UP and SUPER UP symbols apply to Coin and Sticky Coin symbols first. After collecting, Coin Collect sticks until the round ends.
One chain from the rules: a Mystery lands, a Mystery UP hits the row over that reel, and the symbol becomes a Mystery Jackpot. At the end of the round it opens as Mini, Minor or Major.

Coin Up Volcano Bonus Shop
The Bonus Game costs 30x Base Bet in the shop, the Mega Bonus Game 75x and the Ultra Bonus Game 150x. Mega adds more SUPER UP symbols, and Ultra adds many more.
A bought round plays at Base Bet and starts right after the purchase. Sticky Coins already on the reels stay out of a purchased Bonus Game, so let a natural trigger collect them first. The shop blocks a purchase when the balance is too low.
| Option | Cost | at $0.10 Base Bet | at $1 Base Bet | What changes |
|---|---|---|---|---|
| Bonus Game | 30x Base Bet | $3.00 | $30 | Standard Hold and Win round |
| Mega Bonus Game | 75x Base Bet | $7.50 | $75 | More SUPER UP symbols |
| Ultra Bonus Game | 150x Base Bet | $15.00 | $150 | Many more SUPER UP symbols |

Playing Coin Up Volcano on a Budget
In a Coin Up Volcano online session, 3 lines triple the spin price, and one Bonus Game purchase costs 30x Base Bet.
Fix the bet and line count for the whole session so Sticky Coins survive until the bonus triggers. Any coins stacked up before a purchase stay out of a bought round.
| Budget $50 | Cost | How many |
|---|---|---|
| 1 line at $0.10 Base Bet | $0.10 per spin | 500 spins |
| 3 lines at $0.10 Base Bet | $0.30 per spin | 166 spins |
| Bonus Game buy at $0.10 Base Bet | $3.00 per purchase | 16 purchases |
Demo Game vs Real Money
The demo runs on a fun balance with the same rules, the same 1 or 3 lines and the same Bonus Shop. Use it to watch how Reel UP opens locked cells and how many re-spins a typical bonus lasts before placing a real bet.
At a Coin Up Volcano casino, spins cost $0.10–$90.00 in USD and wins can be withdrawn. That range comes from the demo configuration, and a given operator may set different limits.
