DoubleUp
Tap. Merge. Double up.
Tap a group of three or more matching tiles to merge them into double the value. Build combos, climb the number ladder and beat your best score.

What is DoubleUp?
DoubleUp is a merge-number puzzle on a 5×7 board. Every tile shows a number. Find three or more connected tiles with the same number and tap once: they merge into a single tile worth double. Bigger groups pay more, new record tiles pay coins, and the number ladder climbs with you, so there is always a bigger tile to chase. A run lasts a few minutes. Getting really good takes a lot longer.
How to play DoubleUp
Find a group
Look for three or more connected tiles showing the same number.
Tap to merge
They collapse into one tile worth double. Bigger groups pay a combo bonus.
Claim rewards
Each new highest tile pays coins. Watch an optional ad to double them.
Keep the board alive
A run ends when no three connected tiles match. Use a booster, or start a fresh run.
Boosters
Lives & coins
- You hold up to 5 lives; each new run costs one.
- A life comes back on its own every 30 minutes.
- In a hurry? Watch an optional ad for an extra life, or refill with coins.
- Each new record number pays coins. Coins buy boosters and refills; optional coin packs and an ad-free option are in the shop.
- Ads are never required to keep playing.
DoubleUp in action




A new challenge every day
Once a day, DoubleUp builds a challenge board out of the date itself — there is no per-player shuffle, so everyone who plays today's challenge starts from the exact same board. It changes at 00:00 UTC. Your challenge score is kept separate from your normal best score, so a rough run never touches your record.
Daily check-in
Open the game each day to claim that day’s gift and keep a check-in streak going through a seven-day cycle, with the reward growing as the streak runs. The day rolls over at 00:00 UTC, and missing a day starts the streak again from day one.
Leaderboard
Two boards sit at the bottom of this page: best score this month, and today’s challenge. Anyone can read them without signing in. The board shows a shortened name and a country — never an email address.
Good to know
Is DoubleUp free?
Yes. DoubleUp is free to play in your browser. Optional coin packs and an ad-free option are sold in the shop, but nothing is required to keep playing.
What does the MIN / MAX bar do?
It shows the number ladder for your run. As your highest tile grows, the smallest numbers retire from the board and score their value on the way out, so the board never fills with tiny tiles.
How do lives work?
You hold up to 5 lives and each new run costs one. A life comes back on its own every 30 minutes. In a hurry, you can watch an optional ad or spend coins for a refill.
Is my progress saved?
Yes. Coins, boosters and your best score are saved to an anonymous account automatically. Sign in with Google once to keep them across devices.
Does everyone get the same DoubleUp challenge board?
Yes. The board comes from the date and the game, with nothing mixed in from your account, so every player who opens today's DoubleUp challenge starts from the same board.
Can I read the DoubleUp leaderboard without signing in?
Yes, both boards are open to read. Signing in with Google is only needed to have your own name appear on them.
What happens to my DoubleUp check-in streak if I skip a day?
The streak starts again from day one. Nothing else is affected — your coins, boosters and best score stay exactly where they were.
