There is some confusion among players as to the rules respecting Gifts in Free Facebook Games. The Games themselves sometimes contribute to the confusion actually and although many games share the same rules, some are different. Of the Games that I have explored, the Rules where Gifts are concerned appear to be as follows:
1 Free Gift can be sent to a Friend/Neighbour every 3 Hours. Other players have confirmed the time limit. If any one has been unable to send another Gift after three hours, please let me know.
Players can find items in the Market that have a 'Send' as well as a 'Buy' Option, allowing them to send items to Friends. This is different from the Free Gifts Menu, where ALL Gifts are Free. I expect there are no time restrictions on the Items that can be sent from the Market.
CAUTION: Reciprocating with a 'thank you Gift'. In Farmville, when you send a thank you gift, it will be the SAME item that was sent to you. When this item is one that you specifically requested and which may not be useful to the person who sent it to you, do NOT activate this option. Many of the Free Gifts, such as Materials for Building or for the Tuscan Wedding have NO resale value! If your Friend or Neighbour cannot use the item, it is worthless and prevents you from sending a Gift he/she might appreciate far more.
Free Gifts are unlocked according to the Level of Experience of the Sender.
There are some special situations in Farmville when specific Items that do not appear currently in the Gifts Menu can be requested by a Message on the Player's Wall or by a Request to any Friends who have not played Farmville yet. At least, this was my own experience when I needed Bamboo. Bamboo is one of the Limited Edition Items that is included in the Gift Menu on a cyclical basis. When it did not appear currently in the Gift Menu, I was able to make a Request to a list of Friends who did NOT play Farmville or at any rate never had sent me a Gift before.
The Gift Menu in Farmville includes both Items that are permanent and Items that are cyclical and belong to a special Category. Collectibles, Building Materials and Special Event Items are cyclical. In other words, a Harness and Nails may appear for two days, and then be replaced by Horseshoes and Boards.
There is no time limit nor are there any restrictions on the number of Free Gifts that you can send to a Friend or Neighbour. As with other games, however, when you send a Thank you Gift, it will be the same item that you received. What is interesting here is that Limited Edition Items that have expired can be exchanged indefinitely if you continue to use the Thank you Gift option! For example, the Sunset Tree no longer appears in the Free Gifts Menu as it was a Solstice Item but if you receive one as a Free Gift, you can send one back as a Thank You Gift!
All Free Gifts are available to a player at any level.
One Free Gift can be sent to any/every Neighbour or Friend every 24 hours. Gifts are unlocked by the Level of the Sender. There is a very interesting and useful option in Farm Town that does not exist in other Games, however, which is that you can EXCHANGE any Gift upon receipt of it for any other Gift that YOUR Level has unlocked. I love this option. I only wish this game had better graphics. It is the ugliest game I currently play!
One Free Gift can be sent to 15 Neighbours or Friends every 24 hours. You cannot send more than 15 Free Gifts to ANY ONE in any 24 hour period. In Lovely Farm, the Gift Menu includes both Free Gifts and Paid Gifts. Some of the Paid Gifts are Items that do not appear in the Shop Menu and can be obtained only if some one sends them to you. It appears that there is no time restriction or limit to the Paid Gifts you can send to any individual but I must confirm this.
One Free Gift can be sent to any Neighbour or Friend every 24 hours. A special Gift that does not appear in the Gift Menu will be sent to any one who responds to an Invitation to join a player's Army. I do not think an Invitation bars a Player from sending an Item from the Gift Menu during the same 24 hour period, but I must confirm this.
Gifts are not level-specific but often are part of a set that must be completed before they will be of any use to the recipient.
Free Gifts include Seeds as well as rather unique and rare Animals, including Penguins, Koala Bears and Kimodo Dragons.
