wonder if that's how Yukiho learned her hole-digging skills.
hahahaaaa
But seriously it's like a slot-machine that never stops spinning and never stops showing you whether you're winning or not and plus you get to watch a cool movie that responds to how well you're playing non-stop it can be crazy addictive.
For games like this you can sit there playing through different route after different route and keep going to the atm machine/teller/clerk get more metal balls in your bucket, come back, keep playing and before you know it there goes your rent/tuition/food money for the month.

Plus these pachi-slot games are almost never allowed to released in any other medium (exclusive license for the content for pachi-slot) so the only way to see the scenes is to keep putting those metal balls in!
Of course now we have things like nico and youtube, but it's likely the Yamaguchi and Sumiyoshi syndicates will assign associates to harassing video sites to make sure those scenes stay exclusive. So when it comes out, any scenes that will be up, be sure to download them! They'll probably be pulled very soon! And maybe some poor うploader is going to get his kneecaps busted or a baseball bat in the face!

Here is a short nsfw (a small bit of female sort-of-nudity) real life gif about how serious pachinko is:

Pachinko: it eats souls. IMAS fans in Japan prepare to be impoverished!
