TestTubeGames has released Agent Higgs, a new puzzle game for iOS devices. With the world's largest particle accelerator (the LHC) searching for the Higgs particle, the forefront of physics is often in the news. This engaging game aims to give the players a background in the Standard Model of Particle Physics, which in turn will lead to a better understanding of current discoveries. The game assumes no prior knowledge and is accessible for all players. The game centers on a sliding-block mechanic. By swiping the screen, players slide particles horizontally or vertically. The goal is to use the obstacles and other particles to get a block to Agent Higgs. As more particles and more physical laws are added, the puzzles get increasingly difficult. The game is handcrafted to be challenging and yet engaging.


The story of the game is that Agent Higgs needs the player's help to stay hidden from view. The player moves pieces that are the particles of the Standard Model: electrons, neutrinos, muons, and more. The rules are based on the fundamental forces. Use the Weak Force to get particles moving, or to make them decay. Use the Electromagnetic Force to make particles attract or repel. The physics introduced in this game even extends to matter-antimatter annihilation and neutrino oscillation.


  • Easy to pick-up-and-play
  • Over 100 levels
  • New rules and particles introduced gradually
  • 'Perfect' scores for added challenge
  • No physics background necessary
  • Hands-on experience with the subatomic world
  • Includes all leptons (neutrinos, electrons, muons, and taus)
