Pick a level and how many pages, tick the activities you want in the mix, then press Print (pages are A4, print at 100% scale). The pack round-robins through the ticked activities, so 8 pages across 4 activities gives 2 of each and never two of the same in a row. Level sets the age band for every activity at once: it drives the maze size, how many dots a dot-to-dot has, how high the counting goes, and how squiggly the tracing lines get. A name goes into the titles. Show answers marks the solutions for checking, and is hidden again before you print unless you leave it ticked. An activity that is greyed out needs a higher level than the one you have picked, and is left out of the pack until then. Theme picks the character, or leave it on surprise for a different one on every page, and Style changes how the maze twists. Both re-draw the pack you already have instead of rolling a new one, so you can re-skin a batch you like without losing it.
