Stack
A block drifts left and right above the platform. Tap to release it. Wait too long and it drops on its own — right where it was.

Building
Blocks drift across the top. Tap to drop one. Equal numbers merge — and the whole tower is standing on a platform narrower than it looks.

The whole game
Three verbs. No tutorial.
Everything in Tilt Building comes out of real physics — nothing is on a grid, nothing snaps into place.
Merge
Two 2s touching become a 4. The tower gets shorter, the score jumps, and the new block is bigger and heavier than what it replaced.
Balance
Tilt the phone and gravity leans with you. It steers the falling block — and everything already stacked leans too.
The ladder
Every merge doubles the block. And makes it heavier.
2 → 2048Achievements stop at 2048. The ladder doesn’t.
Score is the sum of everything you merge, and it is also the difficulty clock: Stage 1 starts at 0, Stage 10 at 3,400 points. Each stage narrows the platform and shortens the drop window — and from Stage 8 the platform starts to lean by itself.
The locker
119 skins across five slots.
Blocks, platform, backdrop, palette, sound. A palette is the loud one — it repaints all ten block levels at once. Pick one below and it repaints this page too.

Game tuning
Ten presets, or every constant as a slider.
Gravity, drop window, drift speed and range, platform width, tilt strength, game speed, whether settled blocks rotate — all of it is exposed in a panel inside the game, with tooltips. Nudge one value and the preset name switches to Custom.
| # | Preset | Drop window | Platform width |
|---|---|---|---|
| 1 | Zen | 6.0s | 90% |
| 2 | Chill | 5.0s | 85% |
| 3 | Easy | 4.5s | 80% |
| 4 | Casual | 4.0s | 75% |
| 5 | Normal | 3.5s | 70% |
| 6 | Steady | 3.0s | 65% |
| 7 | Tricky | 2.6s | 60% |
| 8 | Hard | 2.2s | 55% |
| 9 | Expert | 1.8s | 52% |
| 10 | Insane | 1.5s | 50% |
Steering feel is global, not per-preset — a falling block handles identically on Zen and on Insane. Runs from any preset submit to the same all-time leaderboard.
Game Center
One score. Everyone. All time.
No seasons, no resets. Play offline and your best run still counts locally — it syncs the next time you sign in. Signing in is optional; everything else in the game works without it.

In-app purchases
Everything for sale is cosmetic.
Gold comes from playing and buys most of the locker. Gems are the scarce currency behind a handful of Legendary items; level milestones hand them out, and you can also buy them. Nothing you can buy makes a block land better.

FAQ
Questions people actually ask
What is Tilt Building?
A physics game for iPhone. Numbered blocks fall onto a narrow floating platform, equal numbers merge into the next one up (2 and 2 make 4), and the tower you are building can topple at any moment. Nothing sits on a grid — every block is a real physics body.
How do you play it?
A block drifts left and right above the platform. Tap anywhere to drop it. Wait too long and it drops on its own, right where it was — so the whole skill is timing. Tilt the phone to steer the falling block and to lean everything already stacked.
Does tilting the phone actually do something?
Yes. The game reads the device roll from CoreMotion and tilts the gravity vector of the whole physics world, so a tilt pushes the falling block sideways and leans the settled tower with it. Lean too far and the stack walks off the edge.
Can I pause a run?
There is a pause button for interruptions, but the drop timer is deliberate: a block will not wait for you forever. The tension is the point.
What are stages?
Difficulty ramps with your score, not with time. Stage 1 starts at 0 and Stage 10 begins at 3,400 points. From Stage 8 the platform itself starts to lean, which is when towers usually come down.
Do I need an internet connection?
No. The game plays fully offline and keeps your best score on the device. Game Center scores and achievements sync the next time you are online and signed in.
Is Game Center required?
No. If you skip it you still get a local high score, levels, skins and everything else — you just will not appear on the global board.
What is the Game Tuning panel?
Every gameplay constant — gravity, drop window, drift speed, platform width, tilt strength, game speed — is exposed as a slider, with ten presets from Zen to Insane. Any run submits to the same all-time leaderboard, whatever preset you are on.
What are gold and gems?
Gold is earned by playing and buys most of the locker. Gems are the scarce currency for a handful of Legendary items; you get them from level milestones, or you can buy them.
Can I unlock everything without paying?
Most of it, yes — the large majority of skins are gold-priced, and level milestones hand out free skin tokens, gold and gems. A few Legendary palettes are gem-priced, so getting those without buying gems takes a while.
Does it work on iPad or Android?
iPhone only for now, portrait, iOS 17 or later. There is no Android version.
What data does the game collect?
None. There is no analytics SDK, no ad SDK, no account and no server of ours — progress lives on your device, and Game Center and purchases are handled by Apple. See the privacy policy for the full text.
It falls over. That’s the game.
One hand. One narrow platform. Physics that doesn’t negotiate.
