Overview

Collisions Higher Education (Collisions HE) is a chemistry game system for introductory and general college courses. It suits instructors who want concept-based activities and class reporting to complement teaching, rather than students looking for an independent study tool. Its range of chemistry topics is useful, but the student subscription and limited support make it a qualified choice.

Key features

Coverage spans more than 55 core concepts, grouped into eight areas: radii trends, ionization energy, acid strength, Lewis structures, ionic bonding, energy in phase change, LeChâtelier, and intermolecular forces. That breadth gives instructors options across introductory and general chemistry, though the games are organized around these particular topics rather than serving as a general-purpose course platform.

Every game combines leveled challenges with an exploratory sandbox. Students can work through directed practice or investigate a concept more freely; molecular modeling and reaction simulation extend the activities beyond conventional drills. Instructors get a dashboard with student progress and performance reports, along with content overviews, quick-start guides, formative assessments, and extension assignments. These classroom tools are most valuable when a teacher actively incorporates the games into a course.

Pricing

Instructor access is free for US-based college and university educators. Student access costs 15.00 USD per year, billed as a 12-month subscription; the normal price is $20.00. Students give up independent enrollment: they register through a unique invitation URL from an instructor, and their accounts are linked to that instructor’s class.

The free instructor plan is a clear fit for eligible educators, but it does not make student participation free. Student accounts are deleted each July 1, so learners should account for that annual reset. The subscription is a poor fit for students outside the supported US college and university audience.

Platforms

Collisions HE supports Android, iOS, macOS, web, and Windows, giving classes several ways to access the games. Platform support does not remove the US-only eligibility or instructor-linked enrollment requirements.

Who it's for

Choose Collisions HE if you teach introductory or general chemistry at a US college or university and want a broad set of game-based activities with class reporting and teaching resources. It is less suitable for independent learners, students seeking free access, or classes that need ongoing direct support from the maker.

Pros and cons

Pros: More than 55 core concepts across eight chemistry areas give instructors a substantial set of course activities.
Pros: Leveled challenges, exploratory sandboxes, molecular modeling, and reaction simulation provide varied ways to engage with concepts.
Pros: Progress reports and supporting teaching materials help instructors connect activities to classroom work.
Cons: Students pay 15.00 USD per year and need an instructor’s invitation to register.
Cons: Access is limited to US-based college and university educators and students, and student accounts are deleted each July 1.
Cons: Playmada has ceased operations and no longer provides email, phone, or training support; users are directed to a support forum. Instructor accounts unused for 12 months are deleted.

Alternatives

Chemistry Simulation Software is a broader directory of chemistry simulation options. Consider these alternatives when their pricing or access model better suits your class:

Beyond Labz offers free instructor access for teaching, previews, and assignment building, plus a 20-week Chemistry plan for 31.95 USD per once. Choose it if that instructor workflow or one-time student payment better fits your needs.
ChemCollective Virtual Lab is free for educators and students to install, use, and distribute. It is a sensible option if free access for both groups matters more than Collisions HE’s game-based concept practice.
Interactive Chemistry provides free web-based games and simulations. Its maker says prototype code is available on GitHub for users to finish themselves, so it suits readers willing to work with an unfinished project.
PhET Interactive Simulations offers free, open-source simulations to students and teachers online or as downloads. Choose it if open access without a student subscription is the priority.
ChemTube3D is a freely available educational resource for Android, iOS, and web. It may suit readers seeking a free option on those platforms.
Molecular Workbench is free and open-source, and is developed and maintained by the Concord Consortium. Consider it if open-source software and ongoing development by that organization are priorities.
PraxiLabs has a free plan with one month of access, three simulations, basic real-time guidance, and English and Arabic interfaces, with no credit card required. Pick it if a limited trial and those interface languages are useful.
MoleculAR is a free Android and iOS app with a free-to-download QR code library. It may suit readers seeking a no-cost mobile option.

Verdict

Collisions HE is worth considering for US college chemistry instructors who want a wide range of concept games, student reporting, and supporting classroom materials at no cost to the instructor. The strongest reason to choose it is the combination of breadth and teacher tools; the strongest reason to look elsewhere is that students pay for class-linked access while maker-provided support has ended.
