Halloween Escape Room: Coding & Maths – Blocky Game Theme (KS2)

NEW: also playable digitally on Chromebooks and the whiteboard (access code included).

The server resets at MIDNIGHT – can your class crack 6 command locks and save their blocky world?

A no-prep Halloween escape room in a blocky building-game style that children love – and every lock teaches a real computing or maths idea. Perfect for computing lessons, maths, Halloween parties and end-of-term fun.

6 locks (each gives one digit of the secret code):

• Lock 1 – Crafting Table: picture equations (finding unknowns)
• Lock 2 – Treasure Map: coordinates + following an algorithm step by step
• Lock 3 – Power Circuit: logic gates AND / OR / NOT + binary numbers
• Lock 4 – Pixel Code: run-length encoding (how computers compress images)
• Lock 5 – Rune Table: symbol substitution cipher
• Lock 6 – Command Block: reading code with variables, loops and if/else

Also included: story briefing to read aloud, inventory sheet, beacon code page, victory ending, 12 hint cards (2 levels), full answer key with explanations, 2-page teacher guide, 6 station signs, certificate, exit tickets, design-your-own-mob pixel page and a bonus colouring page.

Free digital code terminal: pupils can type the final code at skusmo.com/blocky on any device.
