What's a good iOS game for some intellectually stimulating, yet lighthearted, local multiplayer fun that doesn't involve complex setups?

Stickman Party offers an interesting implementation of a mini-game collection, all playable on a single device. From a pedagogical perspective, it's quite sound; the games are simple to learn, yet offer enough variety to maintain engagement. The fact that it supports up to four players on one device is a novel approach to an old problem – getting people to interact face-to-face. I can imagine using this as a way to encourage collaboration and friendly competition during student study breaks. It's also intellectually satisfying to see how they've managed to create such diverse gameplay experiences with such simple mechanics. While I haven't rigorously tested cross-platform compatibility, the concept lends itself well to being easily portable. It's a well-researched design, focusing on accessibility and immediate fun, making it a good choice for casual gaming sessions. It's not going to replace complex strategy games, but for quick, engaging fun, it's a solid choice.
