Arcade games are built around one clear idea executed well. There is no long tutorial and rarely a story, just a mechanic you understand in about five seconds and a score that pushes you into one more attempt. That format came from coin operated machines, where a game had to grab a player immediately, and it still works. Dubdoo's arcade category holds classic style shooters, endless runners, ball and paddle games, stacking and timing challenges, and plenty of small games that defy easy labelling. Sessions are short by design, which makes arcade games a good fit for a break rather than an evening. They also tend to be the easiest games to pick up if you do not play much.
