Crocodile Clips
Simple Simulation Software
Our Products
At Crocodile Clips, we create educational software for schools and colleges.
Yenka 
Yenka is a range of powerful, but easy-to-use, simulation software, covering science, design and technology, mathematics and computing. They let you experiment in a safe, accurate virtual world.
To help students and teachers, we've decided to allow free home use for Yenka - as long as it's not for commercial purposes.
Sumdog 
Sumdog is a website offering mathematics games, which are free to use at home or in school. Each one covers 100 numeracy topics across 10 levels, and most are multiplayer - letting you play with other students around the world.
Teachers can sign up free to create free student logins and set them challenges. Schools can also subscribe to track their students' progress.
Crocodile Simulators
Our Yenka software is built on the simulation engine from our Crocodile simulators - Crocodile Physics, Crocodile Chemistry, Crocodile Technology and Crocodile ICT. Yenka has replaced these products, but if your school currently uses one, you can upgrade.
Crocodile Mathematics is still available, as it covers different topics to our Yenka Mathematics software.
Absorb Courseware 
Our Absorb courseware titles are interactive courses based around our unique simulations, interactive animations and videos, linked by an involving narrative.
Each title offers a huge amount of interactivity - ranging from simple animations that show hidden concepts, to powerful models that allow flexible experimentation.
