Traff Zen

There's an intersection. Trucks coming from the left, buses from the right, a tram cutting through the middle. No one is yielding. You have a handful of signs and a limited number of places to put them. Figure it out before you hit Go. You place traffic lights, one-way arrows, roundabouts, speed bumps — whatever it takes to untangle the mess. The tools are limited, so every placement matters. Then you watch. Either the vehicles flow through cleanly, or something crashes and you start over. Some puzzles are obvious. Others look simple and aren't. You'll move one sign, restart, move it back, try a completely different approach — and eventually something clicks. Six worlds, each with a different layout and feel. A quiet suburb. A packed downtown grid. A school zone with slow-moving traffic. An industrial area where trams don't stop for anyone. The further you go, the tighter the margins. Daily challenge for a fresh puzzle every morning. Achievements, streaks, hints when you need them. No timers, no lives — just the road, the signs, and the problem in front of you.
