Solo Words is a game based on 4 rounds of Word Play Solitaire. Players must play a word in each of the five (5) horizontal word slots. Words must be at least 2 letters and are only limited by the number of letters allowed in each slot. (You can play a 3 letter word in the 5 letter slot) Playing a full word in any slot enables the bonus tiles for the word slot above it. Each round is over when 5 words have been played or the timer runs out.
