Veinlight

Veinlight is a cosy connect-the-gems puzzle set deep inside a lantern-lit mountain mine. Every level is a slice of rock with pairs of matching gemstones: draw a glowing vein between each pair, fill every cell, and watch the whole slice light up.

Each slice is a square grid with gems in two of each colour – ruby, amber, citrine, peridot, emerald, sapphire, amethyst and more. Press a gem and drag your finger through the neighbouring cells to its twin. Veins may not cross or share a cell, and the slice only glows when every vein is joined and no dark cell is left. Draw back to shorten a vein, press anywhere on it to continue, and undo any stroke for free. A lit slice pays crystals, and crystals buy hints from the miners' owl and open the gates to deeper mines.

KEY FEATURES
✓ 120 crafted slices across 8 mines, growing from a gentle 5×5 adit to wide 12×12 caverns
✓ Three late-mine rules that change how you plan: timber bridges where two veins cross, ore marks that only one colour may fill, and twin stones that end two veins at once
✓ A Gemdex of 32 gemstones, each with its own painted specimen, hardness, colour notes and a short story from the mine
✓ 30 miner's badges for steady lamps, long veins, bridge building, daily streaks and more
✓ A fresh daily slice every day with a weekday twist – Bridge day, Ore day and Twin day – plus a lantern streak
✓ Records for every grid size: best times, cells of vein drawn, hints used, bridges crossed and time underground
✓ An illustrated field guide with animated diagrams for every rule, and a friendly owl with tips when you are stuck
✓ Soft clay-style art: chunky gems, timber props, minecarts, stalactites and an underground lake, lit by warm lanterns

HOW IT WORKS
1. Enter the mountain and pick a mine – Lantern Adit is open from the start.
2. Join every pair of matching gems with a vein and fill the whole slice.
3. Light the slice without help to keep all three lanterns burning.
4. Spend crystals on an owl hint when a seam is stubborn, or save them to open the next mine gate.
5. Collect the gems hidden behind special slices and complete your Gemdex.

THE EIGHT MINES
Lantern Adit, Ruby Gallery, Cart Junction, Trestle Drift, Stalactite Hall, Mirror Lake, Winch Deep and the Crystal Cavern. Each mine has its own painted scene, its own four gems and its own pace, and the deeper mines mix every rule together on the largest slices.

WHY VEINLIGHT
Veinlight is calm and unhurried. There are no lives, no energy bars and no timers forcing you on – the clock is only there if you want it, and you can switch it off. Gem symbols can be turned on so colour is never the only cue, motion can be reduced, and sound and haptics have their own switches. Every slice ships with a valid solution, so there is always a way to light it.

PRIVACY
Veinlight works fully offline. No account, no ads, no in-app purchases and no data collection – your progress stays on your device. Crystals are earned only by playing.

Pick up your lantern, follow the glow, and light every vein in the mountain.
