Eye-Comfort Ball Sort: Calm

A quiet puzzle about sorting mixed balls into single-colour glasses. Instead of a stark white background and saturated colours, everything is painted in warm paper tones and a muted botanical palette — easier on your eyes late at night and through long sessions.

■ Easy on the eyes
• A warm paper background with quiet sage green accents
• Twelve muted botanical colours — Brick, Moss, Eucalyptus, Indigo and more
• A glass full of a single colour is marked quietly, with a gold rim
• A low-glare board built to stay comfortable however long you play

■ One tap to move
• Tapping a glass lifts its top ball
• It only lands on a ball of its own colour, or in an empty glass
• Drag and drop works too, if that is how you think
• A run of the same colour travels together, in one move

■ Hints that never point into a dead end
• A hint is a move the solver picked after actually working the board out
• So following one can never strand you somewhere unwinnable
• If a board truly can no longer be solved, the game says so
• Undo steps back as far as the first move

■ 100 stages, three colours up to twelve
• Colours are added a step at a time as the stages climb
• Every stage is proven solvable before you ever see it
• The same stage always deals the same board — restart and it is that board again
• Clear all 100 and you can move freely between any of them

■ Two ways to play
• Classic — every ball shows its colour, all the way down
• Hidden — only the top ball of a glass keeps its colour; the rest are question marks
• Balls you move or uncover stay face up, and so does a finished glass
• A hundred boards of its own, drawn fresh off the same difficulty curve
• Switch from the mode button up top; each mode keeps its own stages and records

■ Three stars against par
• Clear time, moves and par, side by side
• Par is a true floor, not a guess: one move can merge at most two runs of colour
• The closer to that floor you land, the more stars

■ Sound and touch
• Distinct sounds for lifting, landing, finishing a glass and clearing a stage
• Three sound steps — off, soft, normal
• A light buzz as balls lift and land — switch it off in settings

■ Light and undemanding
• No sign-up and no login
• Plays without an internet connection
• Your stage progress and settings stay on your device

One colour at a time — take it quietly.
