Wit sharper than any sword.
— Said of Tenali Raman
Adaptive math practice featuring 69 puzzle types and step-by-step explanations.
About
Tenali is named after the legendary Tenali Raman—the witty Indian scholar who outwitted entire courts with logic rather than just facts. The platform is built on this very idea: math isn’t memorized; it’s outwitted.
In Adaptive mode, Tenali adjusts the difficulty as the learner answers.
Tenali covers foundational arithmetic, geometry, algebra, everyday maths and calculus basics, with practice drills, hints and step-by-step solutions. Live and free at tenali.fun.
Why it works: Maths questions are generated on the fly with varied numbers, so practice is different every time. The 69 puzzle types cover arithmetic, geometry, algebra, calculus and everyday maths such as percentages and GST, plus two quizzes, vocabulary and general knowledge, which draw on fixed question sets. Learners choose Easy, Medium, Hard or Extra Hard, or let Adaptive mode decide.
A learner moves through four stages in every session:
Land on the home grid at tenali.fun and browse the topic cards, or search for one. No sign-up is needed.
Choose a topic, then a level: Easy, Medium, Hard, Extra Hard or Adaptive, and how many questions you want.
Solve 20 questions by default. Type each answer on the keypad, and tap "Solve" anytime to see the worked solution.
At the end, see your final score and each answer with the time it took, then play again.
The Problem
Math anxiety is a cycle that starts early and compounds over time. Endless repetitive practice doesn’t build intuition; it just builds memory.
What We Built
Tenali flips the model. Pick a topic and get a question. Maths questions aren’t pulled from a static list; they are generated on the fly, and in Adaptive mode the difficulty follows what you have just shown you know. A single, unified engine powers 69 puzzle types, spanning arithmetic, geometry, algebra, calculus, vocabulary, and general knowledge.
Key Features
Choose Easy, Medium, Hard or Extra Hard, or pick Adaptive and Tenali adjusts the difficulty as you answer.
When you are stuck, tap Solve to see the method and each step worked out.
Quick drills for functions, dot products, fractions, linear equations, indices and polynomials, plus an all-in-one adaptive gym.
Random Mix is a cross-topic adaptive challenge. Custom Lesson lets you pick the topics for your own quiz.
Multiple-choice vocabulary and general-knowledge quizzes with three difficulty levels, drawn from fixed question sets.
Free for everyone, with no ads. The code is open source on GitHub.
