A set of games built for GCSE Computer Science on the OCR J277 specification. Each game covers a real exam topic — drag components, trace algorithms, decode binary, defeat logic gates. Play through them all and you'll have both papers covered before you even open a revision guide.

OCR Spec J277 Paper 1 · Computer Systems Paper 2 · Algorithms & Programming

Paper 1

Computer Systems
▶ Play ⚙️
Build a Computer
Drag the CPU, RAM, ROM, GPU and storage onto the right motherboard slots. A popup explains each component when you get it right.
Systems Architecture
 ▶ Play 🔢
Binary Blitz
Convert denary to binary and hex against the clock. Four levels, unlocked as you go, with worked-method hints.
Number Systems & Data Representation
 ▶ Play 🌐
Spot the Threat
Identify phishing emails, malware, brute force attacks and social engineering in a series of realistic scenarios.
Network Security
Coming soon 🔄
CPU Cycle
Step through the fetch-decode-execute cycle one instruction at a time and answer a question at each stage.
Systems Architecture

Paper 2

Algorithms & Programming
Coming soon 📋
Trace Table Challenge
Step through pseudocode line by line and fill in the trace table. The game checks each cell and explains mistakes.
Algorithms & Programming
Coming soon 📊
Flowchart Builder
Drag process boxes, decision diamonds and arrows to build a working flowchart, then watch it run.
Computational Thinking
Coming soon 🏁
Sorting Race
Watch bubble sort vs merge sort race on a shuffled list. Predict the next step before it animates.
Algorithms
Coming soon 💡
Logic Gate Puzzles
Given a True/False output, work backwards through AND, OR and NOT gates to find the correct inputs.
Boolean Logic
