Chess Clock Neo

Whether you play 1-minute bullet on the bus, study openings with a 15+10 rapid clock,
or run a club tournament with Classical 40/90+30 — Chess Clock Neo handles every
chess time control out of the box. Beautifully crafted, fully customizable, and
100% ad-free forever.

⏱ EVERY TIME CONTROL

• Sudden Death — fixed time bank
• Fischer increment — bonus seconds after each move
• Bronstein delay — used delay time is refunded
• US-Delay — per-move delay timer before the main clock ticks
• Multi-stage / Guillotine — e.g. 40 moves in 90 min + 30 min, with optional
per-move increment in either phase
• Japanese Byo-yomi — base time + N reserve periods
• Canadian Byo-yomi — periods with fixed move count
• Hourglass — time spent flows to the opponent
• Move Timer (Gong) — fixed seconds per move
• Scrabble — clock counts past zero into negative time

🎨 CUSTOMIZATION THAT GOES DEEP

• Drum-roll wheel pickers for every time value — no fiddly sliders
• Full HSV color wheel with editable hex input for pixel-perfect tuning
• 15 hand-tuned theme presets: Midnight, Daylight, Neon, High Contrast,
Forest, Ocean, Sunset, Ice, Lava, Grid, Vapor, Plasma, Toxic, Cyber, Aurora
• Per-player color control: background, text, animated border, border thickness
• Animated 3D shrinking border that retracts proportionally to remaining time
• Per-player rotation (0° / 90° / 180° / 270°) for face-to-face play
• Horizontal or vertical split

🏆 TOURNAMENT-GRADE EXTRAS

• Long flag tone when time runs out or a period ends
• Tap click and haptic feedback — each toggleable independently
