Highlights

• One-handed play. Choose left or right hand and the number keys and actions gather on the side your thumb reaches. "Easier reach" lets you play without stretching to the top rows.
• Hints that teach. A hint does not just give the answer; it explains, step by step, which technique to apply. Practice each technique with examples in the Learn tab.
• Daily streak. Solve today's puzzle to keep your streak going.
• Five difficulty levels. From Easy to Master, each tuned to the techniques it requires.
• Notes, undo, mistake checking. Pencil notes, undo/redo and an adjustable mistake policy.
• For everyone. Light, dark, high-contrast and color-blind-friendly themes; phone and tablet layouts; Turkish, English, Russian, French, Spanish, German, Italian, Portuguese, Polish, Dutch, Finnish, Hungarian, Romanian, Vietnamese, Bulgarian, Greek, Japanese, Korean, Arabic and Persian.
• Plays offline. Your progress and statistics are stored on your device; the app has no server of its own.
