Flip Stack
Help & Support
Need a hand with Flip Stack? Email support@greenfieldlabs.llc and tell us your device model, iOS or Android version and what happened. The answers below cover the most common questions.
How do I play?
Drag a stack of pancakes from the tray at the bottom onto an empty plate. When the top pancakes of two neighbouring plates are the same flavor, they flip together onto one stack. Ten or more of one flavor on top of a stack get served, which frees room and counts toward the order shown at the top. Fill the order to win. The NEXT panel shows the three stacks that will follow your current tray, so you can plan ahead.
I ran out of plates
A level ends when no empty plate is left for a stack. You then have a choice: use a Fork or a Spatula you own to free a plate and carry on, revive by watching an ad or spending coins (a revive clears at least five stacks, the most mixed first), or give up and try the level again. Every opening is checked so that it can't trap you in your first moves, and a level you keep losing gets a little gentler.
What do the boosters do?
The Fork eats one stack and frees its plate. The Spatula moves a stack to an empty plate, or a single-flavor stack onto a stack with the same flavor on top. Shuffle deals you a new tray. Boosters unlock during the first levels; you earn them from win streaks, chests, the festival and the Café Race, and you can buy them with coins.
Stars, coins and the café
Winning a level pays coins and stars; Hard levels pay more of both. Stars and coins rebuild your café one item at a time, and each item comes in several styles. Coins also buy boosters and revives. Daily Treats, the Chef's Chest, the free gift and the piggy bank on the home screen give extra coins and boosters.
Spicy Kitchen and the Café Race
Spicy Kitchen opens at level 12 and is optional. With it switched on, your win streak sets the heat: hotter levels start with fewer open plates (never fewer than three), bigger orders and more mixed stacks, and pay more coins and, at the higher heats, extra stars. The Café Race opens at level 15: win 8 levels within 24 hours, ahead of four other chefs, for coins, boosters and a trophy. The other chefs are part of the game, not other players, and their pace is fixed when the race starts. Finishing first moves you up a league, where the chefs are faster and the prizes bigger.
I can't tell some flavors apart
Open Settings (the gear on the home screen) and turn on Flavor Symbols. Every flavor then also has its own symbol on the pancakes.
Change the language
Flip Stack speaks English, Spanish, Portuguese (Brazil), German, French, Japanese and Korean. It starts in your device's language when it is one of these, and English otherwise. To change it, tap the gear at the top left of the home screen, then Language; Device language follows your phone again.
I bought something and didn't get it
Open Settings or the Shop and tap Restore Purchases. This restores permanent items: No Ads and the Starter Pack. On Android, Google Play also gives them back by itself on a device signed in to the same Google account. Coin packs and Break Piggy Bank are delivered when the purchase completes; if one didn't arrive, close and reopen the game while connected to the internet, then contact us if it's still missing. If a purchase needs approval (Ask to Buy, or a payment that completes later on Google Play), the item arrives once it's approved.
Can I get a refund?
Refunds are handled by the store you bought from. On iPhone, request one from Apple at reportaproblem.apple.com. On Android, follow Google's steps in Request a refund on Google Play.
Where is my progress saved?
Your progress is saved on your device, including the level you are in the middle of. If your device is signed in to iCloud (iPhone) or Google Play Games (Android), the game also keeps a copy in your own account while Settings > Cloud Save is on, so reinstalling the game, or playing on another device signed in to the same account, continues where you left off. Turning Cloud Save off asks whether to keep the copy in your account or delete it. Without a cloud copy, deleting the game deletes your progress and we can't recover it, although restoring a backup of your device that includes the game brings it back. Permanent purchases can always be restored with Restore Purchases.
Reminders
If you allowed them, the game reminds you when something is waiting, such as your daily treats or the end of a Café Race. To stop them, open iOS Settings > Notifications > Flip Stack, or on Android, the notification settings for Flip Stack (Settings > Apps > Flip Stack > Notifications; the wording varies by device).
Ads, the age question and privacy
Ads come from Unity Ads through Unity LevelPlay. Once you've reached level 8, an ad can appear after a level you win, at most once every 90 seconds; never during a level or after a loss, and there are no banners. You can also choose to watch one for a reward: a revive, a booster, double coins or a doubled daily treat. Buying No Ads turns off the ads between levels; ads you choose to watch for rewards stay available.
On your first visit to the home screen from level 5 on, the game asks what year you were born (and the month, only if the year isn't enough). The answer stays on your device and is never sent to us or to the ad network, and ads don't start until it's answered. Players under 13 get only ads that aren't based on them and never see the tracking question. In the EEA, the UK and Switzerland, players at their country's age of digital consent then choose between personalised and non-personalised ads; you see the same number of ads either way, and you can change your choice at any time in Settings > Ad Choices. On iPhone, players 13 and older are asked Apple's tracking question once (unless they get non-personalised ads); you can change your answer in iOS Settings > Privacy & Security > Tracking. On Android, you can reset or delete your advertising ID in your device's settings.
Players 13 and over (in the EEA, the UK and Switzerland, from their country's age of digital consent) can turn play statistics (which help us tune the levels; no names, never used for ads) on or off in Settings > Share Play Data, and Settings > Delete Play Data asks Unity to delete what your device has shared; your progress stays.
Most test versions on TestFlight or a Google Play testing track show the game's own placeholder ads, labelled as mock ads, which load nothing. See our privacy policy for details.
