Jeu Sum 15 | Jeu éducatif Montessori STEM de mathématiques pour enfants

The wooden disks feel solid in your hand and slide onto the board smoothly, which makes the whole thing feel less like a cheap toy. My 7-year-old picked up the "first to make 15" rule in one round and now begs to play it after dinner instead of asking for the tablet.

My kids fight over who gets to play first every night now—it's that good. The turn-based disk placement is simple enough for my 6-year-old but still keeps me on my toes trying to block her moves. Honestly, it's the rare game that feels like both a lesson and pure fun.

My 7-year-old actually asks to play this, which says a lot since she usually fights me on math practice. The turn-taking with one disk at a time keeps it simple enough for her but I still have to think about my moves. Only wish the box were smaller so it'd fit better on a shelf.
