About Block Dominoes
Our Mission
PlayBlockDominoes.com exists to do two things: let you play a correct game of Block Dominoes in a browser against computer opponents, with nothing to install and no account, and explain the game in pages that only say things you could check against the tiles or the rules.
It is a one-person project, not a company. The site is free and supported by advertising. There is no online play against other people, no ranking and no account; what you see is the whole product.
History of Dominoes
Tile games with pip-marked pieces have a long history in China, where the sets differ from the European one: 32 tiles, no blanks, and some tiles duplicated. The 28-tile double-six set with blanks that Block Dominoes uses appears in Italy and France in the 18th century. The two families are related in idea but not in rules. The stories that give dominoes an exact birth date, an emperor in 1120 or a pharaoh's tomb, circulate widely without evidence, and our history article says which is which.
Older European tiles were often bone or ivory with dark pips, which is the look the tiles on this site are drawn to resemble.

Educational Value
Beyond entertainment, Block Dominoes is a genuinely useful teaching prop. Counting pips is arithmetic practice, judging what an opponent is likely to hold is an intuitive introduction to probability, and deciding between two legal plays is a small exercise in reasoning under uncertainty. Those are descriptions of what the game asks of you, not claims about lasting cognitive gains.
Observational research has linked frequent participation in board games to a lower incidence of dementia in older adults, though such studies cannot establish that the games are the cause. We look at that evidence, and its limits, in our article on the cognitive benefits of dominoes.

About the Author
Dave Albert
Founder & Developer
Dave is a software engineer and the person behind PlayBlockDominoes.com. He built the site because he wanted a clean, ad-light, browser-based version of the classic block game — something that ran well on a laptop or phone and didn't bury the gameplay under pop-ups and signup walls.
Everything here — the game engine, the AI opponent, the rules pages, and the blog articles — is written and maintained by Dave. He isn't a tournament-circuit player, so the strategy posts lean on published references and clear examples rather than personal war stories. When an article makes a claim about cognitive benefits or probability, it links to a source readers can click through to verify.

How the pages are written
The strategy pages are derived from the rules and the arithmetic of the set, not from tournament experience, because the author has none. Each number sits on seven of the 28 tiles; nobody draws; a pass therefore proves something. Most of the strategy on this site is worked out from those facts, with the positions shown so you can check the reasoning tile by tile.
Where an article makes a claim that does not follow from the rules, it cites a source you can read, or it says plainly that the claim is a story without evidence. The one article that touches on health, on the cognitive benefits of games, is limited to what its three cited studies support and says what they do not show.
Corrections: the rules page and the game engine are meant to agree exactly, and every worked example is meant to add up. If you find one that does not, email the address below and it will be fixed, with the page's “last updated” date changed to say so.
