2. One Tap Duels – One hit duels became a thing for a while in android and this game in particular, really stood out for me. One Tap Duels combines 2 things that I love. Samurai duels featuring Pirates, Spartans, Ninjas and Samurais and that oh so nostalgic pixelated graphics. The game is pretty fast paced and it tests you reflexes and timing and with these combined, it brings about all the tension that a sudden death duel could possibly bring. One of the perfect games to kill time with.
