Odd Signal

Give your eyes a five-minute pattern-spotting workout after a demanding day. Find the odd signal, master 24-round Trails, and battle friends live.

Your day was full of screens. Give your eyes five focused minutes.

Odd Signal is a calm visual puzzle where the rule changes every round. One moment you are looking for a different hue; the next hides a different shape, arrow direction, or number of dots. Read the rule, find the break, and keep your accuracy sharp.
