Player Testimonials

"I was instantly hooked, and knew I would be staying for a long time, even though I never was a gamer. Most online games seem to be about combat, or Lord of the Rings type role-play, and neither ever interested me. Sleuth is as a game quite different, and also appeals to different skills like logic, memory, management, social interaction and teamwork."
-Nicole (Age 31, Amsterdam, The Netherlands)

"Never playing an online video game before, stumbling across Sleuth was one of the best things that could have happened. From there, I tried out other online games, but none compare to Sleuth. The game is highly interactive, challenging, and intellectual as well."
-Ryan (age 15, Michigan)

"Sleuth is the best on-line game currently available to those of us who are not “combat oriented.” I tried it on a whim about a year and a half ago, and was totally hooked immediately."
-Cathy (age 51, Michigan)
