Pull back, let fly, bonk the robots

Tie the balloons, snip the strings, float it home

Pull the arm, clear the shelf

Stack it, balance it, hold it for three

Place the parts, launch the ball

Time the bounce, land the trick

Tilt the board, mind the holes

Flick it, mind the fan, nothing but bin

Pull back the ball, bring the house down

Slide, curl and sweep to the button
In a physics game the world behaves the way real things do. A ball flies in an arc, a stack of crates topples when you hit the bottom, a seesaw tips towards the heavier side and a curling stone bends as it slows down. You do not press a button to win; you choose an angle, a power or a place to put something, let go, and watch what happens. Getting it right feels earned, because it was your aim and your timing that did it.
The physics games on Kiloo share a simple shape. Each one has forty hand-built levels in four worlds, booths, offices or clubs, with three stars to earn for doing it neatly. Most show a dotted line or a ghost outline before you commit, so you can read the shot rather than guess. And each one has an endless mode with a high score for when the levels are done. Nothing is violent: robots tumble into a padded pit, glass pops into sparkles and the targets are tin cans and paper bins.
The aim-and-release games are the easiest to pick up. In Slingshot Siege you drag back the slingshot, read the dotted arc and knock robot dummies off wobbly towers of crates, planks and glass. Catapult Cans does the same at a fairground, sending beanbags, bowling balls and bags of marbles into pyramids of tin cans. Paper Toss is the office version: flick a crumpled paper ball into the bin, aiming into the wind from a desk fan. Wrecking Ball swings a big iron ball on a crane chain to bring a cartoon building down below the line.
If you prefer a puzzle to a throw, Balance Beam asks you to place crates, teapots, books and a sleepy cat in a basket on a beam so that it stays level for three seconds. Balloon Lift has you tie just enough helium balloons to a crate or a kitten's basket to float it up to the goal, and snip a string at the right moment. In Bounce Lab you set planks, bumpers, trampolines and portals on a lab bench, then launch the ball into the goal beaker.
Three games are more about touch and timing. Marble Tilt is the wooden labyrinth from the toy cupboard: tilt the board and roll the marble past the holes into the cup. Trampoline Trick asks you to push off at the deepest point of every bounce and throw tucks, pikes and twists in the air. Curling Club is top-down curling, where you choose an in-turn or an out-turn, let the stone go and sweep in front of it.
Almost every game here starts with a drag. With a mouse or a finger you pull back from the slingshot, the catapult arm, the wrecking ball, the paper ball or the curling stone, and let go to throw. The keyboard gives you finer control: the arrow keys adjust angle and power, Space fires, R retries and U undoes the last shot in most of them, and P pauses and M mutes everywhere. Paper Toss also shows a hint when you press H.
A few games are different. In Marble Tilt you tilt the board with the arrow keys or WASD, by dragging, or with your phone's tilt sensor if you switch it on. In Trampoline Trick you press Space or tap when the ring closes on the mat, and keys 1 to 6 throw tricks. In Curling Club you tap or rub the ice ahead of the stone to sweep it.
The main tip is to change one thing at a time. If a shot falls short, add a little power and keep the angle. Watch the dotted preview, and use undo freely, since a retry costs nothing.
Yes. Every physics and skill game on Kiloo is free to play in your browser. There is nothing to download or install and no account to create; press Play and the game starts. Your stars, your progress through the levels and your endless-mode high scores are kept in the browser you play in.
Yes, all ten physics games work on phones and tablets as well as on computers. You drag with a finger to aim and let go to throw, tap to push off in Trampoline Trick and rub the ice to sweep in Curling Club. In Marble Tilt you can even tilt the phone itself, if you turn that option on.
Slingshot Siege is a good first pick: drag, aim along the dotted arc and let go. Catapult Cans and Paper Toss work the same way with a different target. If you would rather think than throw, start with Balance Beam or Balloon Lift, which are quick puzzles about weight and lift.
Yes, in Curling Club. You can play a match against a computer rival at one of three skill levels, or play against a friend with two players taking turns on one device. The other physics games are for one player, with levels to clear and an endless mode for a high score.
The games are gentle by design. In Slingshot Siege the robot dummies land softly in a padded pit, in Wrecking Ball nothing shatters into sharp bits and nobody gets hurt, and the cat in Balance Beam is always set down gently. The harder later levels may need an older child's patience or a parent's help.
