Connect 1–25 in order.
🎯 How to Play
- Choose A & B for both parts, or select Part A or Part B. Try a short practice first if needed.
- Part A: connect 1–25 in order. Part B: connect 1–A–2–B and continue to 12–L–13. Click or tap each circle; you do not need to drag.
- The timer starts when the board appears. A wrong circle does not advance the path, and the timer keeps running. Changing the board size or leaving the page interrupts the current part.

Practice benefits & everyday uses
Visual search & attention
Find the next target among scattered circles. Visual search is also what you use to locate an item in a list, a number in a spreadsheet or an option in a menu.
Cognitive flexibility
Switch between number and letter rules in Part B. Cognitive flexibility is also useful when moving between work steps, applying a changed instruction or returning to a task after an interruption.
Working memory & sequencing
Remember where you are in both sequences and what comes next. Keeping track of progress also matters when following a recipe, assembling something or completing a series of instructions.
The Science Behind the Game
The science behind Trail Making Test practice
The Trail Making Test (TMT) involves visual search, attention and sequencing. Part B also draws on working memory to track two sequences and cognitive flexibility to switch between numbers and letters.
Each connection follows a simple cycle: find the target, act, then update the next step. Try the same deliberate approach when working through a checklist or a set of instructions. In the game, aim for fewer mistakes as well as a faster time.
Screen size, input method and the random layout can affect your time. When comparing rounds, use the same device and consider both completion time and errors.
