This is like a mini connect four - not what I was expecting. I was hoping for a mind puzzle for kids.

This is a great game for a road trip or kids to use on the bus. It’s tick tac toe but with 4 in a row on any side. My son has found many ways to trick me and win. We enjoyed playing and game play is very fast. All pieces all store inside the cube. One thing that would have made it cooler is if the sides opened to be able to check a diagonal. We both seem to have varying ideas of where the pegs should be placed to win on a diagonal.

I originally got these for party favors for my puzzle and game obsessed kid. We opened one and played it, but ended up returning the rest because neither of us enjoyed it. She will play games incessantly and she was done with this after one long, tedious round where we attempted the third game of trying to NOT get four in a row. Neither of us ever did before we even went through TWO colors each.

This game is fun for the kids in the back seat to play on long trips. Took 1 star off because mine only came with 3 different color pegs not 4. Wasn’t a deal breaker as we have 3 kids and they were still able to play together.
