Stack UpTerms of use
Last updated 27 September 2026
Stack Up is a stacking game made by Reynaldo Columna at Overlaydeck. Using it means agreeing to what is on this page.
Using the game
Play it and enjoy it. Do not take it apart to republish it, and do not use tools that alter the game to change your score.
The leaderboards
Today's board inside the game puts you against practice rivals that the game generates each day. They are not real people. Their names and scores are made up, and they reset at midnight.
If you use Game Center, your daily points also go to Apple's Game Center leaderboard, where the other players are real. That board is run by Apple.
Coins and purchases
- Coins are not money. They have no cash value, cannot be exchanged for money, and cannot be moved to another player or device.
- Purchases are handled by Apple. Refunds are Apple's to give, under Apple's terms.
- Coins are spent inside the game, on Slow-mo and on power-ups such as Perfect Pulse. Power-up charges are bought with coins only, never with money, and are used up one per level.
- Coins do not come back. Coin packs are consumable, and the game has no account or cloud save, so coins and power-up charges are lost if you delete the app or lose your phone.
- Reset progress keeps what you paid for. It starts your levels and stars over and clears earned coins and power-up charges, but coins you bought that are still unspent, block skins, achievements, and Remove ads, stay. An achievement's reward is paid once, even after a reset.
- Remove ads does come back. It is a permanent unlock. Tap Restore purchases in the Shop on any device signed in to the same Apple ID.
Ads
Stack Up is free and paid for by ads. The first releases ship with ads switched off; once an update turns them on, there is a banner at the bottom of the screen while you play, and a full-screen ad now and then when you move on after clearing a level. You can also choose to watch a video (up to five a day) to double the coins from a win or to get slow-mo. Those are always your choice. Nothing in the game requires them, and slow-mo can be bought with coins instead.
The ads are served by Google AdMob. We do not pick the individual ads and we are not responsible for what an advertiser says or sells. If you see something that should not be there, tell us and we will report it to Google.
Remove ads is a one-time purchase that turns off the banner and the between-level ads for good. Videos you choose to watch stay available. Nothing else about the game changes.
Buying things cannot buy you a better score. Points come only from what you do in the levels.
Test builds
If you are playing a TestFlight build, it is unfinished. It may break, lose progress, show test ads, or change without notice, and things in it may never ship.
Changes to the game
Stack Up will change. Levels, prices and the leaderboards may all change, and parts of the game may be removed. If a change would take away something you paid real money for, we will tell you first.
No warranty
Stack Up is provided as it is, without warranty of any kind. It is a game. Do not rely on it for anything that matters.
Governing law
These terms are governed by the laws of the State of Florida, United States.
