Build the Periodic Table
Answer a question, earn an element, stack it on your tower. Collect all 118 and learn chemistry without it feeling like studying.
For grades 3–8. Hard and Extreme modes challenge high school chemistry students too.
Learning that stacks up
Every right answer drops a new element block onto a wobbly tower. Reach the finish line to win the round, and fill in the periodic table one element at a time.
Every element
From hydrogen to oganesson. Each block shows its number, symbol and name, so kids see them again and again.
Questions that grow with you
Easy and Medium for grades 3–8, Hard and Extreme for budding chemists. Fun facts pop up along the way.
Blocks with personality
Every element has its own face. They blink, look around, grunt when they're stacked on, and cheer when you win.
Something new every day
A Daily Challenge, practice on tricky topics, and study sets kids can make from the questions they want to master.
No ads, ever
Free to download with a one-time unlock for the full game. No subscriptions, no accounts, no ads.
Private by design
Progress stays on the device. Nothing about your child is shared, and the only purchase sits behind an adult check. For parents
Bring it to your classroom
A teacher plan is on the way: give your class a code, add your own questions and see how students are doing. Pilot teachers get to try it first and help shape it.
