Big Fish is celebrating the Memorial Day (US) holiday weekend by offering a selection of games for only 99 cents. But that's not all we found. In addition, Hidden Expedition: Amazon is also being offered for 99 cents, along with all the previously reported free games. This all adds up to some very inexpensive fun to be had during the long weekend.

Plants vs. Zombies is now available from Big Fish Games for a mere $6.99! That's a steal of a deal for a game that will likely be in the running for Casual Game of the Year 2009.

If you don't already own the unique, puzzle-filled game Azada, or the epic hidden object adventure Hidden Expedition: Everest, or the remarkably fun and challenging Fairway Solitaire, or the time management hit Spa Mania, then you can get the full version for any or all of these titles, FREE! Offer good only until May 31, 2009, so don't delay — do it NOW...
