How to play Plopjar
Plopjar is a free physics merge game for your browser. You fling soft, numbered blobs into a glass jar. When two blobs with the same number touch, they merge into one blob worth double. Keep merging to build bigger blobs and a higher score, and don’t let the jar overflow.
What is the goal of Plopjar?
The goal is to merge matching blobs into bigger and bigger numbers while keeping the jar from filling up. Every merge doubles the blob’s number (1, 2, 4, 8 and so on up to 8,192) and adds points to your score. The game ends if blobs stay above the dashed line at the top of the jar for 3 seconds.
How do you throw blobs?
Plopjar works with a finger on a phone or tablet and with a mouse on a computer. There are no buttons to learn, only drag and release. On a keyboard, the arrow keys aim, Space drops the blob, 1 to 4 (or Q and E) pick a shelf blob and Esc pauses.
- Grab a blob from the shelf. The shelf above the jar holds four blobs. You can pick any of them, not only the first.
- Slide it along the top of the jar to aim. Let go without pulling and it floats down gently where you released it.
- Pull down to throw. Drag down into the jar and release. The further you pull, the harder it flies, which is how you knock blobs apart or reach a gap.
- Change your mind any time. Drop the blob back on the shelf and nothing happens.
- Swap shelf blobs by dragging one onto another. You get one swap after every throw. The small blob at the end of the shelf shows what is coming next.
How does merging and scoring work?
Two blobs with the same number merge the moment they touch. The new blob is worth double and appears where they met. Your score goes up by the value of the new blob, multiplied by your current combo.
| Rule | How it works |
|---|---|
| Merge | Two matching blobs become one blob worth double, for example 32 + 32 = 64. |
| Points | Each merge scores the value of the new blob. Making a 64 scores 64 points. |
| Combo | Merges less than about 1.25 seconds apart chain into a combo. The combo multiplies points, up to ×5. |
| Shelf fusing | Two matching blobs side by side on the shelf fuse on their own and score too. |
| Game over | Blobs above the dashed line for 3 seconds end the game. Zen mode has no game over. |
What do Shake and Pop do?
Merging charges the three dots at the bottom of the screen, and bigger merges and longer combos charge them faster. Each full dot is one power-up, and you can hold up to three.
- Shake jiggles the whole jar. Use it when matching blobs are stuck next to each other but not touching.
- Pop removes one blob you tap. Save it for the small blob that is blocking a big merge, or for an emergency when the jar is near the line.
What are rainbow blobs?
Rainbow blobs are wildcards. A rainbow blob merges with the first blob it touches, whatever its number, and doubles it. They show up rarely, and only after you have made a 16. Aim a rainbow at your biggest blob for the most points.
10 tips to score higher in Plopjar
- Keep big blobs in one corner. Build a staircase from large to small so each new merge lands next to the blob it should join.
- Drop gently by default. A soft release lands exactly where you aim. Save hard throws for breaking up a jam.
- Use the whole shelf. You can pick any of the four shelf blobs. Grab the one that fits the jar now, not just the first in line.
- Look at the next blob at the end of the shelf before you throw, so you know where the following one will go.
- Spend your swap. You get one swap per throw and it does not carry over, so use it to line up shelf blobs that will fuse.
- Chain merges for combos. A blob that merges and then lands on another match keeps the combo going. A ×5 combo scores five times the points.
- Don’t bury small blobs. A lone 1 or 2 trapped under big blobs blocks the jar for the rest of the game. Pop it if you have to.
- Save one power-up for emergencies instead of spending all three as soon as they charge.
- Watch the dashed line. You have 3 seconds once blobs cross it, which is usually enough for one fix: a merge, a Shake or a Pop.
- Practise in Zen. Zen mode has no game over, so it is the easiest place to learn how blobs roll and bounce.
