Perfect to occupy our little bundles in all situations where they have to keep quiet: in the restaurant, in waiting rooms, in airports, in train, etc. Little exos too funny contain quite a bit of French games (mystery word, reorder words whose letters or syllables were mixed, reorder mishmash of phrases include a played back, coded messages, etc.). There are also some logical sequences, mazes, pattern recognition (translation), research from several of the same design proposals, coloring and elementary math exercises on the matter but, I would advise further "small puzzles too malignant," more focused on math, while too funny exos are more oriented towards the mastery of French.
