Hot take: Mental math is a superpower in 2026.

Your phone can calculate. But can you see 7 + 4 + 9 and think “20” in under 1 sec?

King of 20 trains that exact skill.👇🏾https://t.co/WNyA5khJgj

We use math, at some level, every day of our lives but adults across the world struggle with even basic mathematical tasks. @OECD found that Canada and the United States fair the most! Lets turn this stat around by making math fun! https://t.co/JcWj0iyEMQ

King of 20 has officially been submitted for review! We have spent the last few months building King of 20 from the ground up and the last few weeks adding the final touches. We can't wait for you to see the results! #indiedev #education #gaming

An interest in STEM subjects can often start as an interest in gaming and problem solving. We should recognize this and provide encouragement as we close the "skills gap"! https://t.co/alZapJ4hKa #education #indiedev #STEM
