Little Alchemy 2

Little Alchemy 2 starts everyone on the same four elements, air, water, earth, fire, but unlike AI-generated combining games, every result here comes from a fixed, discoverable recipe list, which means a combination that works for one player works identically for everyone.

Because later elements almost always require combining two earlier discoveries rather than base elements directly, working through the game's early, most obvious pairs first tends to unlock the broadest set of ingredients for later, less intuitive combinations. Revisiting an old, seemingly "used up" element against something discovered much later in the tree is frequently how the more obscure results turn up. Infinite Craft runs the same element-combining premise with AI-generated, theoretically infinite results instead of a fixed list.
