Yes. All twelve games, every lesson and the parent dashboard are free. There is no subscription and nothing to buy: the coins children earn are pretend and only unlock outfits, pets and trophies inside ZUNBIX.
No sign-up is needed to play. Your child makes a player with a first name or nickname and a grade, and it is saved in this browser. If you want progress kept across devices, a grown-up can sign in on the parents page. Children never sign in and never give an email address.
No. ZUNBIX shows no adverts, has no chat or messages and no public leaderboards, and shows nothing about your child to other players. The children's privacy page sets out exactly what is stored.
24 math skills for 4th grade: Place Value, Addition & Subtraction, Geometry, Multiplication & Division, Fractions & Decimals, Money & Time, Word Problems. Each one is matched to the Common Core standards for the grade, with hints before answers and a worked explanation after a miss.
31 reading and language skills for 4th grade: Phonics, Sight Words, Sentence Building, Reading Comprehension, Spelling & Vocabulary, Reading Fluency, Grammar, Punctuation, Writing. They are matched to the Common Core English Language Arts standards for the grade.
The grade is only where ZUNBIX starts. A short starting check in math and reading finds the right level, every round moves up or back with your child's answers, and a gap points back to the earlier skill it needs. You can change the grade at any time.
Yes. Read-aloud is on from the start, and every question has a Listen button, so a child who reads slowly can still play every game. It can be turned off in the sound settings.
A practice round is 10 questions, a few minutes. Grown-ups can set a daily goal on the parents page, and the dashboard shows what was practised, what has stuck and what is worth another round.
Yes. ZUNBIX runs in the web browser on computers, Chromebooks, tablets and phones, so there is nothing to download or install.
