Well just a tiny bit of math is needed but the app helps you by showing the factors that each number has. It’s a challenge to try to figure the best sequence which is different each day because the set of numbers changes.Great clear user interface and straightforward operation. Takes just a minute to play or you can replay it for who knows how long to try to match the best possible daily score.

This clever puzzle hits the sweet spot. It’s quick to play but takes some thought, and changes just enough from day to day to stay novel. I love that you can appreciate your score or relay as many times as you want for the highest score. I’m enjoying this as an adult and it would also be a great puzzle to share with students.

What fun! I have always loved Tax Collector, but once you figured it out there was not much left to do. This game is different every day, creating new and interesting challenges, and has me waking up wondering what today's puzzle will bring.

There’s a minor learning curve to get a hang of the strategy, but very fun once you learn it.
