The field guide

Know the route.
Beat the blackout.

Gridlapse is a memory maze by Rhys Austin. You get a brief look at each board, then cross it from memory. Reach the lime goal, survive the faults, and see how far one run can take you.

Three moments. One route.

  1. Read the grid. Find your arrow and the lime goal during the preview. Trace a safe route before the board fades; movement begins in the blackout.
  2. Hold it in your head. Remember the turns as short groups of moves. Avoid red faults and purple path echoes: stepping onto either ends your run.
  3. Make your move. Follow your route to the goal before time runs out. Each goal starts another round, with new positions to remember.

Read the markers

Your arrow
Your position. It turns to face your last movement direction.
Lime goal
Your destination. Reaching it adds one point.
Red fault
A lethal tile. Plan your route around it.
Purple echo
A lingering path hazard. Treat it like a fault.
Gold Glint
An optional extra point. A detour is only useful if you can still reach the goal.

Controls that stay out of your way

On a computer, use the arrow keys or WASD. On a phone or tablet, swipe across the board or tap the directional buttons. Use Pause when you need a break; the timer freezes until you resume.

Sound and haptics can be switched off in the main menu. Restart begins a new run, while Menu returns to the title screen.

A better run starts with a simpler plan

Find the goal first, then choose a route with as few turns as you can comfortably remember. Count moves in groups, such as “two right, three up,” instead of trying to memorise every tile.

Leave Gold Glints alone when the route feels uncertain. A goal and a Glint are each worth one point, but reaching the goal keeps your run going. As the boards get busier, spend your preview time checking the dangerous tiles beside your chosen path.
