OlymCraft: Math Olympiad Prep

OlymCraft helps primary-school students practice math olympiad and competition problems — with real exam timing and step-by-step solutions that actually teach.

Built for parents who want more than a quiz app: your child solves the same kinds of problems as real math contests, then reviews every question to see exactly why an answer is right or wrong.

WHY PARENTS CHOOSE OLYMCRAFT
• Real exam format — a countdown timer and a full-length "real exam" mode, just like the contest.
• Start short, build up — begin with quick 15-minute sessions (8 questions) and work up through 30 and 45 minutes to the full real exam, so primary-school students get comfortable and build skills step by step, without pressure.
• Learn, don't just test — every question has a detailed, step-by-step solution.
• Track progress — see how much your child has practiced and improve a little every day.
• 6 languages — English, Bahasa Melayu, Bahasa Indonesia, Thai, Traditional Chinese and Vietnamese.
• Illustrated questions — hundreds of visual problems for real understanding.
• Safe and focused — no ads, no distractions.

TOPICS YOUR CHILD WILL PRACTICE
• Word problems and logical reasoning
• Mental math, arithmetic and number sense
• Number patterns and sequences
• Counting shapes, squares and line segments
• Geometry and perimeter
• Combinatorics — counting possibilities
• Age, calendar and grid-path puzzles

HOW IT WORKS
1. Choose the contest, your child's grade, the round and a practice length (15 / 30 / 45 minutes, or a full "real exam").
2. Pick the question language.
3. Practice against the timer; jump between questions with the answer sheet.
4. Review the score and read the solution for every question.
