The Gift tile is OP. Having 3 gift on the board allows infinite combos. Match -> Clone -> Match
the gift tile is more than op, you can have 1 and still set up an infinite, because once it clones, you get the ability to get the original back, and the infinite goes as follows.
oo_
GG_ <--
score, then cloning happens
ooG
___ <--
Then so on and so forth
