Pick a sequence and work down the levels
Each sequence is a short, ordered set of levels. Every level locks its own conditions, ends with a local exit ticket, and tells you where to go next. Progress is stored only in this browser.
Local progress
Progress stays in this browser
Staff Spot records only which levels you have completed, your best score for each, how many attempts you made, and the date. There is no account, no student name, and nothing is sent to a server. Clearing progress affects only this device and browser — a different computer, phone, or browser profile keeps its own record.
