Dave Ross wrote to tell me about his print and play game
Euronimoes, which is in its third and final edition (hasn't required any updates in 4 years).
Print and play games are great for time when you are stuck at home, because they: are craft projects (sometimes minimally), free, and usually light, simple, and family-oriented.
Euronimoes fits the bill, as a Euro-style pattern building game, which requires only one or two sets of Dominoes (0-6) and a few poker chips for each player, and the free rules from his site.
On each turn, you take a Domino into your hand, either from a "market" or the draw pile, and then play one from your hand into your personal pattern space (see the above figure, for example). Dominoes in the market cost -1 (you gain a chip) up to 3 chips, while taking a random Domino always gives you 1 chip.
Columns in your space must always form runs up or down (if touching), and you score the lowest tile in each run; lowest score in the end wins. There is also an option to build upwards and take off more points from your score.
That's about it; details are in the free rules.
