What the heck? Unsuspecting, you open the front door wide to find a box containing … a half-dead cat!? Using smart puzzle skills and clever outside-the-box thinking, you can help Kitty Q to escape her peculiar quantum superposition!   Don’t worry—Anna is there to help you. She’s the great-granddaughter of the world-famous physicist and Nobel Prize winner, Erwin Schrödinger. She will help you guide Kitty Q out of the crazy quantum world. Inside the box, everything follows its own curious rules. It really is an odd world here as Anna explains, but together you get to explore her great-grandfather Erwin Schrödinger’s specialist subject: quantum physics. Every puzzle in the game refers to observations, experiments, or phenomena from this totally unbelievable field of science. It’s a whole new world to discover!   So, you’ll get to know… · why some tiny particles absolutely contradict all the rules at times, · which letter will make your math teacher sweat, · how you look in a selfie with a self-styled, half-dead cat!   In Kitty Q, you will discover more than 20 scientific facts about quantum physics that will amaze everyone.  The quantum adventure Kitty Q has been developed in collaboration with the Cluster of Excellence* ct.qmat and is completely free and without ads or in-app purchases—thanks to the funding of the German Federal Ministry of Education and Research as part of the initiative ‘Research in Germany’.   *A Cluster of Excellence is a team of outstanding scientists who explore new challenges and unsolved puzzles. The answers that they find could have a crucial impact on our lives in the future. For ct.qmat, quantum physics takes center stage.

Verdict

The call

The clearest difference is in-app purchases: Kitty Q at none against Drop Flip's 1. Kitty Q also leads on rating (4.9 vs 4.6). Drop Flip's advantage is update cadence (every 2 weeks vs every 13 months) and ratings volume (9.9K vs 398). On price, review sentiment, ads and device support there is nothing between them.
