Lesson 201 – Find the Faker #1 – Digit‑Sum Match Five numbers appear—four share the same digit‑sum; one differs by ±1. Spot the faker.	Lesson 202 – Find the Faker #2 – Digit‑Sum Parity Four numbers have even/odd digit‑sums; one has the opposite parity. Find the outlier.	Lesson 203 – Find the Faker #3 – Divisible by 3 or 9 Use the digit‑sum rule for 3/9 to identify the number that breaks the divisibility rule.
Lesson 204 – Find the Faker #4 – Divisible by 4 Check the last two digits to find the number that is not (or is) divisible by 4.	Lesson 205 – Find the Faker #5 – Repeated vs All‑Distinct Four numbers follow the ‘all‑distinct digits’ rule; one has a repeat. Pick the faker.	Lesson 206 – Find the Faker #6 – All Digits Even/Odd Four numbers use digits that are all even or all odd; one mixes them. Spot it.
Lesson 207 – Find the Faker #7 – Palindrome Check Four read the same forward and backward; one does not. Find the non‑palindrome.	Lesson 208 – Find the Faker #8 – Alternating Parity Digits alternate E‑O‑E‑O…; one number breaks the pattern. Choose the faker.	Lesson 209 – Find the Faker #9 – Monotone Digits Four have strictly increasing or strictly decreasing digits; one is not monotone.
Lesson 210 – Find the Faker #10 – Distinct‑Digit Count Four use exactly three distinct digits; one uses four. Identify the odd one out.	Lesson 211 – Card Sum Challenge Drag single‑digit cards into a vertical addition so the sum matches the two‑digit target.	Lesson 212 – Card Math Puzzles Choose two of five two‑digit cards to satisfy ? + ? = result or ? − ? = result, then Check.
Lesson 213 – Commute Clock Lina’s commute takes X minutes. One time (leave or arrive) is hidden; enter the missing time in h:mm.	Lesson 214 – Time Between Clocks An analog and a digital clock disagree—enter the shortest time gap between them in h:mm.	Lesson 215 – Lesson Time Showdown Guitar vs. drum lessons with start/end times—how much longer is guitar? Answer in h:mm.
Lesson 216 – Symmetry Grid Reflect the red shape across a vertical or horizontal mirror line by clicking squares. Exact match required.	Lesson 217 – Diagonal Symmetry Grid Reflect the red shape across the main or anti‑diagonal (D1/D2) on the grid.	Lesson 218 – Dartboard Total Two‑ring dartboard with ring scores and random hits—multiply and add to find the total score.
Lesson 219 – Factor Bridges Fill the two missing digits so both product links are true at the same time.	Lesson 220 – Read the Ruler Measure a bar on a 6‑cm ruler to one decimal place, even when it starts away from zero.
