## What is Eye?

Sudoku that stays comfortable however long you play. Instead of a stark white grid and saturated colors, the whole board is painted in warm paper tones and calm sage green — easier on your eyes late at night and through long sessions.

■ Easy on the eyes
• A warm paper background with quiet sage green accents
• The selected cell's row, column and 3×3 box tinted softly
• Matching numbers highlighted together, so the board is easy to scan
• Wrong entries shown in a gentle red rather than a harsh alert

■ Three modes
• Classic 9×9 — sudoku the way you know it
• Mini 6×6 — 2×3 blocks, light enough for a spare minute
• Time Attack — one focused run against the clock

■ Four difficulty levels
• Easy · Medium · Hard · Expert
• Time Attack gives you longer as the board gets harder (5 · 7 · 10 · 12 minutes)
• Best score saved separately for every mode and level

■ Tools that keep you moving
• Auto Notes — pencil in the candidates for every blank at once
• Pencil mode — jot your own candidates cell by cell
• Placing a number automatically clears the notes it rules out
• Hint — three per puzzle, for when a cell will not budge
• Undo and Erase — step back at any time
• Keypad count badges — see how many of each digit are left

■ Focus you can watch grow
• A sprout that keeps growing across every game you play — it never starts over
• Every square you work out yourself adds to it, and finishing a board adds more
• Seedling → Sprouting → Deep Focus → Blooming → Perfect Master
• Finish a board and see your clear time, final score and mistakes together

■ Sound and touch
• Distinct sounds for selecting, placing, noting, erasing, hints and victory
• A light buzz as digits go in and come out — switch it off in settings
• Mute the sound whenever you like

■ Make it yours
• Auto-remove notes on entry — on or off
• Highlight wrong entries instantly — on or off
• Three mistakes allowed, with pause and restart always available
• 한국어 · English · 日本語 · 简体中文 · 繁體中文

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

A calm habit for your mind — start with one board today.
