Bohr Blast

Conquer the Periodic Table

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Blast your way through all 118 elements. Learn their names, symbols and how atoms are built, one nucleus at a time. No ads, no tracking. Bohr Blast is an arcade game that teaches the periodic table. Fire antimatter through the gaps between the circling electrons and clear the nucleus of every atom, from hydrogen to oganesson. Every atom in the game is built like the real one, as a Bohr model: the right number of protons, neutrons and electrons, in the right shells. As you play, the elements' names, symbols and structure stick, almost by themselves. WHAT'S IN THE GAME • All 118 elements, in 7 worlds that follow the periods of the table • A fact for every element you clear, and a quick question before the next one • Build atoms yourself from protons, neutrons and electrons • 10 bonus bosses and a final boss, each about a group of the table • Three difficulty levels: Student, Researcher and Professor • Power-ups, a Daily Element and random practice • Your own periodic table that fills in as you play MADE FOR LEARNING • Made by a Danish science teacher for students aged 12 to 16, and fun for younger and older players too • Questions can be read aloud, which helps players with dyslexia • In 18 languages • Works offline SAFE FOR CHILDREN • No ads, no tracking and no account • Progress is saved only on the device • A question for a grown-up comes before the purchase TRY IT FOR FREE The first 11 elements, hydrogen to sodium, are free. One purchase unlocks the full game for good, with Family Sharing. No subscription.

Ratings & Reviews

  • This app hasn’t received enough ratings or reviews to display an overview.

New in this version: • “Play on a computer”: the full game you bought in the app also opens on bohrblast.com, with a code from the app’s menu. • “Just play”: a new setting with no questions between elements or worlds. • Questions about protons, neutrons and electrons now show the particles as small pictures. • Electrons are the same light blue in every shell; the outer shell has a gold ring.
