I'm in search for games my 4 and 7 year old can play that are satisfying, intellectually stimulant and that make them happy. Not the crappy that appears in any search for "games for kids" (I mean stupid games with lots of colors and sound and bouncing pictures of cats).
The experience was not great in any of those games, since they are made for adults, they're somewhat simple to grasp, but then out of nothing they start to add gotchas that I can perceive easily, but not the children (I'm thinking more about the Android games here).
I imagine that the ideal puzzle for children would be a abstract game with easy controls and a linear learning curve, if that makes any sense.
The game should run on Android, Windows or Linux (or in the browser, if that's a thing).
I'm brazilian, so if the game makes use of language then I don't want it (I'll not ask you to find a Portuguese game, if some game has a "Portuguese" version stamped in it then it is probably a shitty automated translation), but maybe it will be useful for someone else, so please don't restrain yourself from posting it here.
