The first impression is
Many people don't like noise in casual-games. They want something that can be understood in 3 minutes, but kept thinking for 30 minutes. P999 Guide seems better for that mood, especially when you're traveling in Karachi or during an evening break in Lahore and want something light.
In P999, puzzle and logic run at the same pace. Instead of showing speed, it gives a slow challenge, and this is its main strength.
