99 Club Studio v1.25.0 — Magic Squares & richer worked examples

Release date: 11 September 2026

Maths Games & Puzzles

Adds a fourth reusable game engine: Magic Squares.

Teacher options:

  • difficulty: Easy / Standard / Challenge;
  • size: Auto / 3×3 / 4×4;
  • puzzle style: Mixed variants / Fill missing values / Find the magic total / Spot & fix the error / Transform the square;
  • number pattern: Auto / classic / shifted consecutive / scaled arithmetic sequence / decimal sequence (Y4+);
  • clue density: More / Balanced / Fewer.

Generated variants are deterministic and validated. Missing-value puzzles use line-equation rank checks so the hidden values are uniquely determined by the shown clues and magic-total constraints. The transform variant applies the same addition or multiplication to every entry and asks pupils to complete the transformed square and determine its new magic total.

Vocabulary clue enumeration

Crossword clues now show answer lengths automatically, for example (5, 5) for a two-word answer. Definitions-only Word Searches show the same pattern when the hidden term contains multiple words or a hyphen. Enumeration is derived from the term at render time rather than stored in the definition database.

Worked examples

Worked examples are expanded into pupil-facing mini tutorials with:

  • a clear goal;
  • rules;
  • worked steps;
  • a practical tip;
  • a common mistake / watch-out.

Examples are now laid out at up to two games per introductory page, so larger game libraries can add several worked-example pages at the start of a pupil pack without shrinking every example into an unreadable tile.

Compatibility

No changes to the public 99 Club maths engine, Custom Worksheet question families, coordinate/pie/angle generators, or the 591-entry curated vocabulary database.
