Open Wide Slot Demo by Useful Gaming

Open Wide by Useful Gaming Slot Overview

Open Wide by Useful Gaming fills a cartoon mouth with colourful teeth. Its tumbles share the cascading mechanic of Sweet Fiesta, but here winning teeth pop out and extra sets grow, turning the playful dental theme into an expanding playing area.

During Tooth Fairy free spins, extra sets stay in place while Fillings build a persistent pillow multiplier. High volatility and a maximum win of 10,000x the bet give this expanding-mouth slot its risk profile. Explore how the features interact in the free demo on BonusTiime.

Open Wide Slot Features

Open Wide includes Toothache, Big Mouth, Pliers Spin, The Tooth Fairy, Super Fairy, Wisdom Tooth, Diamond Tooth, Eye Tooth, Filling, and the Extraction, with each one changing how the mouth builds ways, wilds, and free spins.

Toothache

Toothache is a feature spin that stays active until you switch back to normal spins. It makes Eye Teeth land far more often, and the Tooth Fairy arrives about 6x as often. That gives the game a stronger scatter-focus without changing the base mouth layout.

Big Mouth

Big Mouth is another persistent feature spin, and it starts every spin with 3 sets of teeth. That means 729 ways before any tumble growth begins. It changes the opening grid state rather than adding a separate bonus round, so it feels immediately different.

Pliers Spin

Pliers Spin forces the Extraction on every spin. The game pulls 2 to 4 teeth into wilds, and it removes Gold Rush and Floss from the treatment pool. Because the mode stays on until you turn it off, it gives the mouth a much more aggressive wild conversion pattern.

The Tooth Fairy

The Tooth Fairy starts when 3 or more Eye Teeth land. It awards 10 free spins for 3, 12 for 4, 15 for 5, and 20 for 6 or more. During the round, each Filling in a winning chain joins a pillow multiplier, and the mouth can grow to 6 sets.

Super Fairy

Super Fairy is only available as a bonus buy. It starts with 10 free spins, all 6 sets already grown, and the pillow at x2. That front-loads the strongest version of the bonus, so the round opens with maximum structure before any retriggers or Filling growth happen.

Wisdom Tooth

Wisdom Tooth acts as a wild on columns 2 to 6. It substitutes for every tooth except Eye Teeth and Fillings. The game also uses it as the replacement symbol in The Extraction, so this wild shapes both regular wins and treatment-based board changes.

Diamond Tooth

Diamond Tooth also works as a wild on columns 2 to 6, but it has a stronger board effect. When it lands, the jaw opens to all 6 sets at once, creating 46,656 ways for the rest of that spin. In free spins, those sets stay until the round ends.

Eye Tooth

Eye Tooth is the scatter symbol and it counts anywhere when a chain of tumbles ends. In the base game, 3, 4, 5 or 6 Eye Teeth pay 3x, 5x, 20x or 100x the bet and start The Tooth Fairy. They do not pay by themselves during free spins.

Filling

Filling is the multiplier symbol. In the base game, it can land at x2, x3, x5, x10, x25, or x50. In free spins, it can land at x1, x2, x3, x5, or x10. When a winning chain ends, every Filling on the board adds together.

The Extraction

The Extraction is a random treatment that can trigger before wins are counted. It pulls 1 to 3 teeth from columns 2 to 6, then grows a Wisdom Tooth into each empty socket. On Pliers Spin, it becomes stronger and pulls 2 to 4 teeth instead of using the normal treatment mix.

Bonus Buy

This section lets players buy the available bonus entries before the round starts. Each option asks for confirmation, then launches the feature with the stated setup and free-spin count.

• Toothache: x3 the bet per spin; Eye Teeth land far more often and the Tooth Fairy comes about 6 times as often.
• Big Mouth: x2 the bet per spin; every spin starts with 3 sets of teeth, so 729 ways.
• Pliers Spin: x5 the bet per spin; the Extraction pulls 2 to 4 teeth into wilds on every spin.
• Buy Tooth Fairy: x100 the bet; one spin, then 10 to 20 free spins.
• Buy Super Fairy: x300 the bet; one spin, then 10 free spins with all 6 sets and the pillow at x2.

Open Wide Slot Review

Open Wide builds its identity around a cartoon dental clinic, with a giant mouth, teeth as symbols, and a playful colour palette that keeps the theme instantly readable. The tooth motif, Eye Teeth, and treatment style give the slot a clear visual hook without overcomplicating the screen.

The main strength sits in the way tumbles and growing sets of teeth stack together, then feed into the Tooth Fairy round. High volatility and the 10,000x cap give the game proper upside, while Toothache, Big Mouth, and Pliers Spin add variety instead of leaving the base game to carry everything.

Open Wide offers feature buy play, while the Tooth Fairy round lets the mouth expand to 6 sets and keeps Fillings and retriggers in play.
