Connect the pairs
Drag from one character to its matching partner to draw a trail between them.
Lifting your finger midway erases the unfinished trail (no penalty)

Trail
A path-drawing puzzle where you connect matching BrainType character pairs with trails that never cross.
Overview
Link Trail is a path puzzle where you connect matching BrainType character pairs scattered on the board. Trails run only horizontally and vertically, and can never cross other trails or obstacles. Erasing a confirmed trail to redraw it costs a +3s penalty. Higher levels add a focus gauge: going too long without a useful move erases your latest completed trail. You race to connect every pair, and higher levels bring bigger boards, more pairs, and more obstacles.
How to play
02
Trail rules
Trails move only horizontally and vertically, and cannot pass through other trails, characters, or obstacles.
While dragging, move back one cell to shorten the trail
03
Black cells are obstacles
Cells with a black background are obstacles. Trails and characters cannot pass through them, so route around them.
Higher levels add more obstacles, so read the whole route before drawing
04
Redraw penalty
Tap a finished trail to erase and redraw it, but each erase adds +3s.
Plan the whole layout before drawing to save time
05
Focus gauge
At higher levels, going too long without a useful move erases your latest completed trail. If there is no trail to erase, it adds +2s as hesitation time.
Move a trail, connect a pair, or redraw to refill the gauge
06
Clear condition
Connect every pair to clear. Leftover empty cells are fine.
Higher levels bring bigger boards, more pairs, and more obstacles

Abilities you'll build
Processing speed
Drawing the obvious connections quickly and cutting hesitation time trains processing speed.
Working memory
Holding the remaining pairs and the shape of free cells in mind while you draw trains working memory.
Reasoning
Planning a full set of non-crossing routes before you commit trains reasoning.
Self-control
Double-checking each route before drawing to avoid redraw penalties trains decision control.
