Merrymakers in neighbors’ towns yield 3 Festive Hats
and 1 Bauble for the first 9 taps, but only 1 of each for the remaining 41 taps. 50 taps in total or approximately 17 neighbors. This yields a total of 68 Festive Hats and 50 Baubles.
Note: While I have confirmed the number of friend actions in my game, others report numbers as low as 45.
You and your neighbors are limited to gifting
5 Presents in a single town at a time. You get 5 Presents every 24 hours. They do not rollover. (You can not hold onto more than 5 at a time.)
The Naughty and Nice minigame is not too complicated. One neighbor chooses Naughty or Nice when dropping a Present in another town, and that other person also makes a choice between Naughty and Nice. A broken version of the Prisoner’s Dilemma, it tempts a player to gift Naughty, which yields the highest reward of 25 Bows if the other neighbor is Nice, where they will get only 1 Bow. Playing Nice on both sides yields 15 Bows for each player. Lastly, playing Naughty on both sides yields 5 Bows each.
The general rule is to play Nice. Not only is this mutually beneficial, it yields a greater total over time, with a player more likely to gift a Present if the risk of getting only 1 Bow is low. With only 5 Presents available to gift per day, the risk of a wasted gift is too high to play Naughty as a strategy.
Presents can be dropped off at Other Springfield. There is no guarantee as to how the gifts are opened there. It is assumed to be random. Either way, it is not as beneficial to play there as it does not help your actual neighbors, nor are any Presents ever gifted back.
