How high can you stack in 3 minutes? One clock for everyone, the same slabs for every player. Drop the slab, keep the overlap. Tallest tower at 0:00 wins the round.
Site rulesHow it works
- Floor 1
Join any time
Paste your public address and jump into the live round. You stack until the shared clock hits 0:00.
- Floor 2
Drop it on the line
A slab swings over the tower. Tap, click or press Space to drop it. Whatever hangs over the edge gets cut off, so the next slab is smaller. Land it dead on and it stays full size. Four perfects in a row and it starts growing back.
- Floor 3
Tallest tower wins
Miss the tower and it comes down; a new one starts right away. Your tallest tower in the round is your score. The server replays every drop and measures it.

Ask the foremanFAQ
How do the rounds work?
Rounds follow the clock: 12:00 to 12:03, 12:03 to 12:06, and so on, all day. Join whenever you like and stack until the round ends. With less than 10 seconds left you wait for the next one.
You can join one round up to 3 times with the same address. Your best run counts.
How is the height measured?
In slabs. Each slab you land is one level. When a slab misses the tower completely, that tower is done and a fresh one starts 1.6 seconds later. Your score is the tallest tower you built in the round. Ties go to whoever reached that height first.
The slab speeds up as the tower grows. A drop within a hair of the slab below snaps on as a perfect ("Level!"), and from the fourth perfect in a row each perfect widens the slab again.
What do winners get?
Whatever the prize note in the live round panel says. There is no pot and no automatic payout: the dev reviews winning runs and sends prizes by hand from the coin's creator fees. Nothing is guaranteed, not an amount and not a date.
When the dev reports a payout, its transaction shows next to the winner with a Solscan link. That's reported by the dev, not checked by this site.
How do you handle cheating?
Your browser never reports a height. It sends the times of your drops, and the server rebuilds the same slabs, replays every drop and measures the towers itself.
Drops less than 60 ms apart, drops before a slab appeared, or a run longer than the time since joining are rejected. Runs that look odd (almost every drop perfect, a giant tower) are flagged, and the dev replays winning runs before paying. A careful bot could still look human, so treat the board as provisional.
Do you need my wallet or a signature?
No. Stack It Higher never connects to a wallet, never asks you to sign and never sends a transaction. It only needs a public address. If you paste something that looks like a private key or a seed phrase, the page blocks it and sends nothing.
Use a wallet you control, not an exchange deposit address. A prize sent to a wrong address can't be reversed.
What do you store?
Your public address, your runs (drop times, so they can be replayed) and a salted hash of your IP address, used only to limit joins. No cookies, no analytics. Your address and settings stay in this browser.
Can I practice?
Yes. Practice needs no address and no server, with or without a 3:00 clock. Your best timed practice is kept in this browser.
