Sparkvali: Light Puzzle

Sparkvali is a calm puzzle about strings of festive lights, inspired by the sparkle of Christmas and the glow of Diwali.

Every puzzle starts as a tangle of bulbs and wires. Drag any bulb anywhere on the board. When no two wires cross, the whole string lights up. Each bulb glows brighter as its own wires come clear, so you can see your progress as you play. Most puzzles take one to three minutes.

How it works
• Touch a bulb and slide it. There is no grid and no time pressure.
• Dashed, pulsing wires are still crossing another wire. Solid wires are clear.
• Junction plugs and power hubs carry many wires, so moving them changes a lot at once.
• Clear the last crossing to light the string.

What's inside
• 120 levels across six worlds, from six gentle bulbs to forty, on a winding world map.
• A new daily puzzle, the same for everyone on the same date, with a streak calendar and best times.
• Two skins: Winter Lights and Festival Lanterns.
• Free, unlimited undo, plus three free hints a day. A hint moves one bulb to a helpful spot.
• Earn up to three stars per level, keep a daily streak, and beat your best moves and times.

Comfortable to play
• Colour-blind-safe palette. Crossed wires are dashed as well as coloured.
• TalkBack descriptions, a "describe board" action, and a step-by-step way to move bulbs without dragging.
• Reduced-motion setting, which also follows your system animation setting.
• Optional sound, gentle ambient music (off by default), haptics, and a hidden timer.
• Light and dark themes. Text scales with your font size.

Private by design
