スライドブロックde懸賞 - パズルde懸賞(公式)

Since it just released, I thought there'd be demand, so I posted my invite code on X. Four people have already used it, and I got the rewards, which makes me happy. Though I didn't win the actual prize draw...

It's a bit tricky at the start, making tons of mistakes, but once you get the hang of it, you can do it pretty well and get hooked.
