Pattern Hunter · Lesson 3
The Number Game Challenge
Meet the Rule Keepers — machines that follow one secret rule each. Feed them numbers, study what comes out, and crack the code.
Welcome to the arcade! 🕹️
Each Rule Keeper machine follows exactly one secret rule. Feed it any number and it answers instantly — but it will never tell you the rule. To beat a machine you must test it, spot the pattern, and prove you cracked it.
This is real mathematician work: scientists poke at mysteries with experiments exactly like this.
🧠 The detective's trick
Don't feed random numbers — feed clever ones:
- Feed it 0. Whatever comes out was added (0 × anything is 0).
- Feed it 1, then 2. How much did the answer jump? That's your multiplier clue.
- Test your guess with one more number before you claim victory.
Game 1: Crack the Machines 🤖
Feed each machine at least two numbers, then hit "I cracked it!" — the machine will test YOU with a challenge number. Beat all three!
Game 2: Speed Round ⚡
No feeding this time — just the machine's records. Read each in→out table and pick the rule.
Game 3: BE the Rule Keeper 👑
Now flip it: build your own machine and stump a friend or family member. Pick a secret rule:
🏆 Your XP Progress
- ○ Cracked all 3 machines +10 XP
- ○ Won the speed round +8 XP
- ○ Built your own machine +7 XP
Total XP earned: 0 / 25
