“It counted better than you. It will show you how.”
All-Fives Dominoes vs a Trained AI · 18 min · Punishing
All-Fives dominoes against a policy network trained by self-play through twenty-two generations. It sees exactly what you see and knows nothing about your hand — when it beats you, it is because it counted better. Coach Mode shows you the count it made. Standard rules by default, plus RaceHorse and other variants, at two, three or four seats.
Why ambitious players love it
A self-play-trained opponent that sees only what you see — no peeking at your hand
Coach Mode: the AI explains the count behind every move it made
Standard All-Fives by default, with RaceHorse and two further variants
Two, three or four seats — the three-hand game plays nothing like the two
An ELO rating, so "getting better" is measurable rather than a feeling
A rules page that covers all four modes, because they genuinely differ
How to Play
- 1
Play a tile so the open ends sum to a multiple of five — that sum is your score
- 2
Watch what the AI declines to play; it is telling you what it holds
- 3
Count the board before you commit. The arithmetic is the whole game.
- 4
Lose a few. Then turn on Coach Mode and find out what you kept missing.

"I lost eleven straight, turned on Coach Mode, and discovered I had been ignoring the fives on the spinner the entire time." — Play-test note, 2026
