Harpoon Pop Tips: Harpoon Timing, Splits and Wave-by-Wave Scoring

Updated October 2026

Harpoon Pop is a dodging game with a single, slow weapon. You stand on the floor, balls bounce around the room, and your only attack is a line that shoots straight up from where you are. Each hit makes the problem bigger before it makes it smaller, because a big ball splits into two, then four. This guide explains how the harpoon behaves while it rises and after it sticks, how high and how fast each ball size moves, what every wave is worth, and how to organise the chaos so the last small ball is popped before anything touches you.

The harpoon: a rising line, then a short wall

Touch anywhere on the play area and your character walks toward the horizontal spot under your finger at its top speed, about one and a half screen widths per second; dragging keeps it following your finger. Each new touch fires from wherever the character is standing at that moment, not from your finger, and a second finger fires without changing where you walk. The harpoon is not a bullet but a full vertical line from your head up to its tip, and any ball that overlaps that line is hit, whether it touches the tip or the shaft.

Only one harpoon can exist at a time, and while it exists, new taps only move you. A rising harpoon that hits a ball is used up immediately, so you can fire again right away. A harpoon that reaches the ceiling without hitting anything sticks there for 0.65 seconds before it disappears. The climb itself takes about two thirds of a second on any phone, because the harpoon's speed is measured in screen heights: 1.4 per second.

The stuck harpoon is the most underused tool in the game. For those 0.65 seconds it is a solid wall from floor to ceiling, and unlike the rising version it is not used up by a hit. A ball that runs into it splits, and if one of the two pieces then travels into the line before it vanishes, that piece splits or pops too. Firing a harpoon in the path of a ball that is heading toward you, rather than at the ball itself, often gets two or three pops for one shot.

The flip side is the reload cost. A miss that sticks to the ceiling ties up your only harpoon for the climb plus the stick time, roughly 1.3 seconds in total. Low shots that hit a ball quickly free the harpoon again in a fraction of that time.

Ball sizes, heights and speeds

There are three sizes. Big balls are worth 10 points when hit and split into two medium balls. Medium balls are worth 25 and split into two small ones. Small balls are worth 50 and vanish. Ball size is set relative to the width of the board, so the balls take up the same share of the screen on every phone.

Each size has its own fixed bounce. Measured from the floor, a big ball peaks at 68 percent of the room's height, a medium at 50 percent and a small at 35 percent. Because gravity is also scaled to the room, the timing is the same everywhere. In our calculation a big ball takes about 2.3 seconds from one floor bounce to the next, a medium about 2.0 seconds and a small about 1.7 seconds. A small ball therefore stays low and bounces quickly, which is why small balls are the ones that actually catch players.

Sideways speed never changes during flight, except that the side walls reverse it. A ball is not slower at the top of its bounce in the sideways direction; what slows there is the vertical motion. The top of a bounce is still the easiest moment to aim at, simply because the ball is barely moving up or down and sits at a predictable height for a moment.

When a ball splits, both pieces start from the same spot, one heading left and one heading right, each at 90 percent of the parent's sideways speed. They are thrown upward at about two thirds of the speed of a normal bounce, so the first hop after a split is clearly lower than usual, and then they settle into their normal bounce height.

What each wave contains and what it pays

A wave is cleared when every ball is gone, which adds a 100-point bonus and starts the next wave after a short pause. The opening waves grow quickly and then hold steady in size:

Every big ball you start with is worth 260 points by the time its whole family is gone: 10 for the first hit, 50 for the two medium pieces and 200 for the four small ones. Since a wave can only end when every ball is popped, the points inside a wave are fixed. There is no speed bonus and no penalty for taking your time, so the only way to score more is to survive more waves.

What does keep growing is speed. The starting sideways speed rises with every wave, and at wave 11 the balls cross the room in a little over half the time they did in wave 1. From wave 6 onward the count stays the same, but every wave after that is a faster version of the last.

Getting hit and what resets

You have three lives. If any ball overlaps your character, you lose one, the screen flashes for a moment, and the current wave restarts from scratch: you return to the middle and the original set of balls is spawned again. The points you scored during that attempt are taken back, so your score returns to what it was when the wave began. In other words, a hit sends you back to the start of that wave with fewer lives and the same score you had then, not to the start of the game. When the last life goes, that start-of-wave score is your final score.

Note that the action begins the moment you press Start. Balls bounce whether or not you touch the screen, and a ball will reach a character standing idle in the middle within a few seconds, so be ready to move as soon as you begin.

Positioning: work one family at a time

The worst situation in this game is eight small balls bouncing low in every direction. You create that situation by splitting everything you can reach. A calmer approach is to finish one family before starting the next:

Your character crosses the whole width in well under a second, much faster than any ball, but it does have to walk there and cannot pass through a ball on the way, so dodging is about choosing a safe spot early rather than running at the last moment. Look for the gap between two balls' landing points and move there before they come down, not as they arrive.

Shot timing

Because the harpoon takes about two thirds of a second to reach the ceiling, a ball high in its bounce is hit late in the climb, while a ball near the floor is hit almost instantly. A good shot is one where the ball will be crossing your position when the harpoon passes its height. For a ball moving sideways toward you, fire a little before it arrives overhead. For a ball moving away, either let it go or move ahead of it and fire.

The corners deserve care. A ball that reaches a side wall turns straight back at the same sideways speed, so a corner is only safe right after a ball has bounced off that wall and is heading away. Standing in a corner while a ball approaches leaves you nowhere to go, because you are pinned against the wall.

Common mistakes

Firing straight at a ball that is directly overhead is the most common error: the ball splits and both pieces drop around your head on their low first hop. Step aside first, or fire into the ball's path from one side. The second mistake is wasting the harpoon on long misses that stick to the ceiling while a small ball is bouncing toward you. The third is splitting all the big balls at once in an early wave, which turns a calm wave into a crowd of small, fast bounces. Patience costs you nothing in this game, since the score for a wave never changes; a hit, on the other hand, costs you everything you scored in that attempt.
