The whole class discusses what to guess, debates strategy, and learns from the colour feedback. mini nerdle works well for younger students or shorter time slots; classic nerdle suits older groups.

pro nerdle – design your own puzzle by entering the solution yourself. Make it as easy or difficult as you like, then share the link with your class. Good for differentiated challenges or homework.
ready-made challenges – pre-built sets of nerdle challenges at varying difficulty levels.
Mental arithmetic, order of operations, logical deduction, systematic problem-solving, and comfort with mathematical notation. The competitive and game-based format keeps students engaged in a way that traditional worksheets often don’t.
