A genuine platform game, not a quiz — a chip character climbs a tower of platforms (Fetch, Decode, Execute, ALU, Cache and more), jumping higher the more CPU questions you answer correctly in a row.
Full description:
CPU Climb is a proper platformer, not a quiz dressed up as one: a chip-shaped character stands on a tower of platforms, each labelled with a stage of CPU operation. Every question answered correctly makes the character jump — and the jump gets bigger the longer the correct-answer streak runs, animated live on a canvas scene with a genuine parabolic jump arc. A wrong answer breaks the streak and the character stumbles in place. The whole climb is built entirely around OCR spec 1.1: the fetch-decode-execute cycle, CPU components (ALU, Control Unit, registers), the three performance factors (clock speed, cores, cache), and embedded systems — with the CPU Core waiting at the summit.
• 45 auto-marked questions, 100% focused on OCR spec 1.1 (systems architecture) — no padding from other topics
• A real platform-game mechanic: streaks of correct answers unlock bigger jumps (1, 2 or 3 platforms at once), visualised with a live animated jump arc
• Covers the fetch-decode-execute cycle, CPU components and registers (ALU, Control Unit, MAR, MDR, PC, Accumulator), the three performance factors (clock speed, cores, cache), and embedded systems
• Career progression through six climber ranks (Ground Level to Core Conqueror), XP, coins and unlockable badges
• A Field Manual (glossary) of every key CPU term, linked directly to the OCR specification
• Every question includes a full worked explanation, not just a correct answer
• Runs as a single HTML file: no login, no install, works on any school device
Use it as a high-energy starter or plenary purely on CPU content, as a focused revision tool before questions on systems architecture come up on Paper 1, or as a reward activity that’s still 100% on-spec.
