The oldest version of series game about pink hair girl Nikki as i've ever known. This game was popular since the time i was in secondary school ( now I'm the senior of university), it's been a very long time tho.
There are reasons why this game is popular. Simple but gorgeous 2D graphics, interesting storyline, varieties of events , and the most known might be the toughness of the game. It's basically is a normal fashion game where you can chill and dress up , but beside that to pass the stages sometimes they require pieces of clothes that need a lot of garments to craft into, and the limited times to sweep the princess stages ( there are 2 modes of stages : maiden (easy/normal) and princess (hard) ) don't forget that drop rates in those stages are very low so you need a lot of time to finish a piece of clothe to afford requirements of the stages. You must be patient and it makes the game very good in my opinions.
In Love Nikki , you don't need to pay much to have many clothes, in case of you craving for sources like energy, diamonds, even golds (money in this game is really important, clothes in the shop are not really expensive but imagine you have to buy lots of the same once to craft fashion then you have to pay gigantic amount of money lol) . Or you can join guild and contributes resources or join with other members to craft gorgeous and powerful sets.
About the gachas drop rates are kinda average. Stable gachas are free (mostly one time spin) , two of them is whenever you logged in , and the other 3 which contains more powerful pieces of clothe will free in 48 hours .
I mean it's totally OK for not paying you can enjoy the game totally free. Thing you need is patient.
Sum up, i really love the game.
