Smallest First
📊 There's a smart way to line things up! In Swap by Hand, swap bars only with their neighbors to sort from smallest to largest — match the minimum moves to earn a ✨. 🤖 In Like a Computer, watch how a machine sorts step-by-step. Compare mixed and sorted lines to see that swap counts change, but comparison counts stay the same — computers can't see ahead without checking! 🎯 In Set Rules, pick your sorting style. Without rules, 100 might strangely end up before 9 — build your own to see why! Made with code · Remix it to create your own line!
Counting with 0s and 1s
🔢 Computers store everything using just 0s and 1s! Turn 8 light bulbs on and off to add place values—watch 4 + 1 and parseInt("00000101", 2) both equal 5 side by side. 🔤 In Secret Message, turn 3 rows of bits into numbers, pick matching letters, and reveal hidden words! Pick the wrong letter and you get funny gibberish. 🎚️ In Bit Shift, solve puzzles to learn how shifting bits left doubles a number and shifting right halves it—moves are limited, so simple addition won't cut it. This app was made with code too · Remix it to create your own secret message!
