Enter the Items Shop on various holidays (Christmas, The Fourth Of July, Halloween) or your birthday to find new items.
Don't lose coins when playing high-low
Always pick 6 and if Snaky picks the number 1 click something to end the mini game quickly and keep your coins. Also, if you pick 6, 1 is the only number that can make you lose coins.
Easy Money
Watch the credits until they end, then wait until they finish again to get 50 Coins.
High-Lo Mini-game
Always pick "7". The game usually chooses a high number, and the worst you can lose is 5 Coins if it selects "1".
New Items
Change the system date to a different time or date in order to get new items in the shop. This works well for going back to a date that you missed, or forward to a date that you cannot wait for (for example, Christmas).
Shantae Background
Touch the Ping Pals logo exactly at midnight (00:00:00) when the chime sounds to unlock Shantae's sexy background in the "Backgrounds" section of the Items Shop. Note: Try setting the system clock fifteen seconds before midnight to give you enough time to prepare to do this.
