Circuit Courier

Circuit Courier is a compact logic puzzle where you rotate wire tiles on a small grid so the current flows from a battery to every bulb before the charge meter drains. Each board mixes straight wires, corners, T-junctions, and the occasional cross piece. The first 30 seconds of every round are intentionally simple: a single battery, a single bulb, and three misaligned wires that show you what one tap can do. Daily mode bundles five hand-authored boards picked deterministically from the UTC date, so every player sees the same set on the same day. Endless mode draws from the harder pool and tightens the charge budget the deeper you go. A clean clear awards three things: the base board points, a remaining-charge bonus, and a rotation-efficiency bonus that rewards solving with as few rotations as possible. Boards are designed to run quickly on mobile. Tiles use SVG glyphs rather than canvas, so rotation animations stay sharp on small screens, and the layout reflows down to a 360px viewport. Daily completion, your current streak, and your high score live in local storage on your device. Nothing about your runs is sent off-device.

One-Shot Ricochet

One-Shot Ricochet is a physics-based arcade game that challenges you to clear all targets with a single bouncing ball. A pointer continuously spins around the arena, and one tap fires your shot in that direction. The ball ricochets off walls, and you must time your shot so the bounces connect with every target before the ball comes to rest. Clear all targets to advance; miss even one and your run ends. Each room introduces new target configurations and demands increasingly precise timing. Early rooms let you experiment with angles and wall bounces, but as you progress, targets cluster in tricky corners or spread across the arena in ways that require careful planning. The pointer never stops spinning, so every shot is a split-second decision between waiting for the perfect angle and risking overthinking. One-Shot Ricochet rewards both patience and boldness. The satisfaction of watching a perfectly angled ball bounce from wall to wall, picking off targets one by one, is deeply rewarding. Short sessions fit easily between tasks, and the escalating difficulty keeps you coming back to beat your highest room count.
