Dont know why people arent really that attracted much when it comes to lottery.Try to look on the current situation of the market now when it comes to gambling field
and you cant see any lottery sites that do sustain or survive for too long due to lack of interest.People are way more attracted with dice and other casino games.
Even i do saw some lotteries that had even a minute result but still it do fail out to gain players thats why i wont be surprised if this one would end on the same fate.
My guess is people want to feel they're in control of what's happening even its all about random (or mostly).
But lottery is different - you can't choose the number you'll be (you can't pick your "lucky" number etc.) so it scares away gamblers.
Btw never heard of lottoshi so never played, can't say much.
