Scientific Games subsidiary Williams Interactive has launched a new online slot game which is the first to powered by the offline hit game engine Close Enough.

In Sea of Tranquility, WILD and BONUS symbols that sit above and below the active reel array are included in any potential line wins and bonus triggers, giving near miss spins the potential to transform into “exciting” wins.

Robin Littleworth, Williams Interactive’s senior director for game development said: “The Close Enough game engine capitalizes on the near-miss experience, which is common in modern slot game experiences, and awards the player on spins that would have just missed in standard slots.

“We’re excited to watch online players enjoy this innovative mechanic that has been a proven performer in land-based casinos for more than a year.”

The game is now available on European sites connected to the Williams Interactive Remote Game Server. It is the first game to be powered by the company’s offline hit game engine Close Enough.
