Start with Secret Codes: one word grid, two different keys, and no way through except trusting each other’s clues. Losing to the deck together beats beating each other, which is why it opens this list and not the duels.
When you do want a rivalry, Bazaar and Mosaic are the friendly kind — ten-minute duels about timing and greed where the rematch button does most of the talking. Lost Ruins runs longer and crueller: every card you throw away is one your partner can take.
Apart for the night? Spectrum works over any call with a phone each, and Word Chain, Nine Letters and Anagram Relay are pair scores against the world — same chain, same rack, one result the two of you own together.

Questions about Games for couples to play online
Which one should we open with?
Spectrum. It takes two minutes to learn and produces the good kind of argument — whether “yesterday’s coffee” sits nearer the hot end or the cold one.
Are these competitive or co-op?
Both, deliberately. Secret Codes, Common Threads, Word Chain and Anagram Relay put you on the same side; Bazaar, Mosaic and Lost Ruins are duels that stay civil.
Which one is best long-distance?
Secret Codes — typed clues, no talking required, and it always ends in a post-mortem. Word Chain is the five-minute version for a lunch break.
What if one of us is better at word games?
Play the pair-scored ones. Word Chain, Nine Letters and Anagram Relay count one result for both of you, so a strong speller pulls the ladder up behind the pair.
