PEG
DROP
Thread the pegs. Land the star.
One ball, a forest of pegs, and a single slot that counts. Set your position, angle and power — then the simulation takes over, exactly the same way every time.

How it plays
Three decisions, then physics.
01
Line up the shot
Slide the ball along the top rail, then dial in release angle and power. Nothing is hidden and nothing is random.
02
Let it drop
Gravity takes over. Air drag bleeds off speed, pegs kick the ball sideways, and glancing hits set it spinning.
03
Land the star
The ball has to come to rest fully inside the starred slot at the bottom of the board. Clipping the lip doesn't count.
The board
Three kinds of peg, and some of them move.
Standard
A measured bounce. Readable, repeatable, and the backbone of every board.
Kicker
Returns more energy than it received. Useful for crossing the board — punishing when you meet one at speed.
Damper
Drinks energy on contact. It will kill a runaway shot, or strand a careful one just short of the slot.
Some pegs oscillate while the ball is in the air — so on those boards, when you release matters as much as where you aim.
Under the hood
A hand-written, deterministic physics engine.
No off-the-shelf simulation. Every force in the game was written for this game, so it behaves the same on every device and every replay.
Gravity
Constant downward pull — the only force you can count on.
Air drag
Speed bleeds away in flight, so long drops land softer than short ones.
Partial elasticity
Restitution under 1 on standard pegs: every contact costs something.
Friction & spin
Grazing contact sets the ball spinning, and spin bends every bounce after it.
Same shot, same result. Always.
The simulation is fully deterministic — no dice rolls, no invisible nudges to make a near-miss feel fair. A miss is information, and the next attempt can use it.
10
Hand-designed levels
Ten boards laid out by hand and ordered on purpose: each one teaches the trick the next one asks for. Scores go to Game Center leaderboards if you're signed in.
Hints are opt-in
The game is free. If a board has you stuck, you can watch an ad for a hint — that's the only ad, and you choose when to see it.
Nothing else in the way
No accounts to make, no in-app purchases, no multiplayer lobby. Open it, play a board, put it down.
Ten boards are waiting.
Peg Drop is built for iPhone and launches free on the App Store.
