Kaboom

Catch every falling bomb with your stack of buckets.

How to play Kaboom

Drag the buckets under every bomb

A bomber slides back and forth along the top, dropping bombs that fall straight down. Move your stack of three buckets with the keys, by dragging on the board, or with the d-pad, and catch every bomb before it reaches the ground. Miss one and it explodes: you lose a bucket and the wave restarts. Clear a wave and the next is faster with more bombs; score a point for every bomb you catch.

Read the bomber, not the bombs

Kaboom looks like a pure reaction test, but the players who last longest watch the bomber at the top rather than the bombs already falling. The bomber slides to its next position before it releases, so tracking its movement lets you get your bucket stack under the drop before the bomb is even in the air. Chasing bombs after they fall works for a wave or two, then the speed climbs past your reflexes and you start missing. Think of it like a fielder in baseball: the good ones move on the swing, not on where the ball lands. You control a column of three buckets, moved with the left and right keys, by dragging on the board, or with the d-pad. Every catch is a point. Miss one and it explodes, you lose a bucket, and the wave restarts, so a careless early drop costs far more than the single point.

Move small, rest smart

Small, precise movements beat big swings. The stack has real width, so a bomb doesn't need to land dead centre; nudging two or three pixels is often enough, and every oversized swing has to be paid back with a correction in the other direction. Between drops, park the stack loosely under the bomber's current position. Since the bomber slides to wherever the next bomb falls, resting near it shortens every move you'll have to make and cuts out most of the frantic side-to-side scrambling. There's a rhythm to learn as well. Bombs fall in a steady stream within a wave, so once you've caught two or three you can feel the cadence and time your slides to it rather than reacting to each bomb as a separate event. When the rhythm breaks, that's your cue that the wave has ended or the bomber has changed pace.

The waves that break people

Early waves are a warm-up. The pressure moments come later, when the stream is fast and two bombs hang in the air at slightly different heights. The rule for those: get under the lower one, catch it, then shift for the second. Trying to split the difference between them usually loses both, because the stack ends up under neither. The other killer is the wave right after a miss. Losing a bucket shortens your stack and rattles your rhythm at the same time, and a lot of runs die two waves after the first mistake rather than on it. Treat the restart as a fresh start: take a breath, find the bomber, and rebuild the cadence from the first drop. Each cleared wave adds bombs and speed while the buckets stay the same size, so the whole game is really a test of how long your reads hold up as the margin shrinks.

Pick one input and drill it

You've got three ways to move the stack, and they reward different habits. The arrow keys give you a fixed sliding speed, which makes them steady and predictable: great for rhythm, weaker when the bomber suddenly jumps the full width of the screen. Dragging moves the buckets exactly where your hand goes, so it has no speed limit, but it invites the oversized swings that late waves punish. The d-pad splits the difference for touch players who want key-style control. None of them is wrong. What hurts is switching mid-run, because your reads are timed to how fast your buckets respond, and changing inputs quietly changes that math. Pick the one that suits your device, then judge your progress by which wave you reach consistently rather than by your one lucky best.

A paddle-controller classic

Kaboom! was an Activision hit in 1981, designed by Larry Kaplan with David Crane drawing the grinning Mad Bomber, a face that became a small piece of arcade-era iconography. The idea traces back to Avalanche, a 1978 Atari arcade game about catching falling rocks, which Kaplan reworked into something with personality. The original was built around the Atari 2600 paddle controller, a spinning dial that let players make the tiny, instant movements the late waves demand; it's a big part of why the cartridge sold over a million copies. Activision even mailed a Bucket Brigade patch to players who could prove a score of 3,000 points. The loop here is the same one that made it so hard to put down four decades ago: a rising wall of speed, always one bad catch away from starting the wave over.

Kaboom: frequently asked questions

What happens when I miss a bomb?

The bomb explodes on the ground, you lose one of your three buckets, and the current wave resets. Lose all your buckets and it is game over.

How do the waves get harder?

Each wave you clear speeds up the bomber and the falling bombs and adds more bombs to catch, so your timing and movement have to get sharper.

What's the best way to stop missing bombs?

Watch the bomber's position at the top and move your stack under its next drop early, rather than reacting to bombs that are already falling. Reacting late fails once the waves speed up.

What happens when I miss one?

The bomb explodes, you lose a bucket from your stack of three, and the current wave restarts from the beginning, so protecting the stack matters as much as scoring points.

Why do the waves get harder?

Each wave you clear drops more bombs and drops them faster. The buckets stay the same size, so your margin for error keeps narrowing until a single slip ends the run.

How do I handle two bombs at once?

Catch the lower bomb first, then slide across to the second. Trying to sit halfway between two bombs at different heights usually means you reach neither in time.

Where should my buckets rest between drops?

Loosely under the bomber's current spot. Since it slides to where the next bomb falls, staying near it shortens every move you have to make.

What was the original Kaboom!?

A 1981 Activision game for the Atari 2600, designed by Larry Kaplan with David Crane drawing the Mad Bomber. It used the paddle controller, a spinning dial that suited the game's tiny fast movements, and it sold over a million copies.
