Flash Coins by Dynabit Gaming is a modern take on a classic 3×3 slot format, combining a minimalist layout with contemporary bonus mechanics and an energetic audiovisual presentation.

The game features a 3×3 grid with traditional slot symbols such as lemons and bells, staying true to the visual language of old-school slots. Despite its compact size, Flash Coins incorporates four jackpots, ranging from a Mini jackpot at 25x the bet up to a Grand jackpot worth 2,000x the bet.

Bonus & Collect Mechanics

The core innovation of Flash Coins lies in its Bonus and Collect symbol interaction, a mechanic more commonly associated with modern hold & win-style slots rather than classic 3×3 games.

• Bonus symbols appear only on the first and third reels.
The Collect symbol appears exclusively on the central reel.

When a Collect symbol lands together with one or more Bonus symbols, the Collect feature is activated. This feature gathers the monetary values of all visible Bonus symbols and adds them directly to the win in the base game, or to the total win during the bonus round.

Bonus Game Structure

The Bonus Game is triggered by landing three Bonus symbols and one Collect symbol.

Once activated:

• The bonus starts with three respins.
• The respin counter resets to three every time a new Bonus symbol lands.
• The Collect symbol becomes sticky for the duration of the bonus.

All Bonus symbol values landing during the bonus are collected and added to the total bonus win. Only spins that produce no new Bonus symbols consume a respin.

Additionally, landing Bonus symbols in the base game can randomly trigger a Boost-style feature, adding extra symbols and potentially completing the conditions required to enter the bonus round.

Bonus Values & Jackpots

Bonus symbols carry fixed monetary values or jackpot identifiers:

• Regular Bonus values typically range from 1x to 15x the bet.
• Jackpot Bonus symbols correspond to Mini, Minor, Major, and Grand jackpots.
• The Grand jackpot pays up to 2,000x the bet.

Bonus symbols that are not collected in the base game are visually transferred upward into a symbolic accumulator area above the grid. This does not affect math directly but adds anticipation and visual continuity — a presentation technique also seen in some RubyPlay titles.

Gameplay Feel & Presentation

Despite a relatively modest hit frequency, the game feels engaging thanks to its simplicity and presentation. Even standard line wins — such as three matching lemons — feel impactful due to strong visual feedback.

Flash Coins stands out through its electrified visual effects and rock-music-inspired soundtrack. Flashing lights sweep across the reels, creating an energetic, almost arcade-like atmosphere that contrasts nicely with the classic symbol set.

The interface also includes a last-win display, allowing players to easily track their previous result in a dedicated window next to the balance.

Comparative Impressions

In terms of overall feel, Flash Coins is reminiscent of ELK Studios’ Freeway 7s. Both games:

• Use a 3×3 grid
• Blend retro slot aesthetics with modern bonus logic
• Rely on strong audio-visual feedback to enhance relatively simple mechanics

The primary difference lies in theme: Flash Coins adopts an American classic-slot style paired with electric rock energy, while ELK’s title leans more toward highway and retro Americana vibes.

Final Thoughts

Flash Coins is a compact yet surprisingly rich slot that proves classic formats are far from obsolete. By layering modern collect mechanics and jackpots onto a traditional 3×3 grid, Dynabit Gaming delivers a game that feels both familiar and fresh.

It is especially well-suited for players who enjoy straightforward gameplay with the occasional high-impact bonus moment, wrapped in an energetic, visually charged presentation.
