Shadestack: Color Sort Puzzle

Shadestack is a calm sorting puzzle. Every color comes in four shades, and each block shows its place with dots: four dots at the bottom, one on top. Tap a tube, tap where its top block should go, and build every stack from darkest to lightest.

HOW TO PLAY
• Tap a tube, then tap where its top block should go
• A block goes on its own color with one more dot, or into an empty tube
• Blocks that are already in order move together
• Stack every color from dark to light to clear the level

HELP WHEN YOU NEED IT
• Undo your last moves
• A hint shows you a good next move
• +1 tube gives you more room
• Restart a level at any time

MADE TO BE COMFORTABLE
• Dots and symbols on every block, so the shades are easy to tell apart
• Light and dark themes, or follow your phone
• No timers: play at your own pace
• Three short lessons teach you everything
