You can buy in game items, such as in SAS Assault Multiplayer, where you are able to use ninja kiwi game coins to buy yourself better weapons to have a better chance of survival. This is only one example out of the many available.
By playing with your face!
There will be a boombot3 game
Yes Boombot is a game on ninja kiwi
freewebarcade or wall of game of ninja kiwi
But with no download...! I believe there's only one way, and that way is to have a glitch happen like say you have 10 ninja kiwi coins by getting some with the wheel of fate. then you add to of then to cart that cost 10 ninja kiwi coins each and then checkout and the next day you might get some if it says -10 or mines 10 ninja kiwi coins where it says your coins well NOW the next day after you done that again you should get allot of coins because that's what happened to me and i came up with... about... 2,02020 i think that's how much i had on my memory and my memory's good but usually i get on memory 1 or 2 numbers wrongs maybe you only get 2,020 instead.
Just play any of the extreme levels when you win the coins are awarded to you
Usually, games will save automatically or there will be slots on a game where you can save your progress. The fact that the game is on Ninja Kiwi does not actually affect this. The problem you may be having is that you are not playing with a logged in gamer account on Ninja Kiwi, instead you are playing as a guest. Simply make an account, and play. This usually solves the problem.
noAh, what great education people have these days. And, to elaborate, a Kiwi is actually a type of BIRD. Ninja Kiwi is a BIRD ninja, and it has nothing to do with monkies what-so-ever. -Source:http://en.wikipedia.org/wiki/Kiwi
Currently, the NK Coin system seems to be down, but when it's back up, NK Coins can be obtained at ninjakiwi and on the Wheel of Fate.
