WIN FAST Company Overview

Features of WIN FAST

A Niche Focus on Games for Asian Markets

Japan Technicals Games (JTG), the studio behind WIN FAST, has developed slots for players in Asia and built a following among them.

The company has concentrated on a segment other providers had not covered: the kind of game that is popular in Asia.

Bonus Sound Effects and Presentation Modeled on Land-Based Machines

Pachislot machines play a distinctive sound effect when a big win is guaranteed. WIN FAST games use the same kind of sound when free spins are triggered and add on-screen prompts taken from those machines, such as “Press the button!” (in Battle Dwarf and other titles), to build excitement.

Hawaiian Dream, the company’s first release, was built with gameplay closely modeled on pachislot machines.

Published Game Specs, Rare Among Online Slots

WIN FAST publishes specs for its slots, such as the probability of triggering a bonus and the chance that a bonus will continue. Few online slots publish any specs beyond the RTP.
