DROP AND MERGE GUIDE
Watermelon Game: an alchemy twist on fruit merging
Drop a small piece, bring matching pieces together and keep the growing pile inside the box. If you enjoy a watermelon game, try Cauldron Drop: our free browser version of that drop-and-merge idea, with ten alchemy materials in a cauldron.
What is a watermelon game?
A watermelon game is a physics-based fruit-merging puzzle. You drop pieces into a container, and two matching pieces combine into a bigger one when they touch. The familiar goal is to work up to a watermelon while leaving enough room for the next drop. Gravity, rolling and the shape of the pile matter as much as the next match.
Cauldron Drop uses this suika-style idea with its own alchemy theme and rules. Dew grows into Spark, then larger materials, all the way to the Philosopher's Stone. There are no fruit pieces in this version. A standard brew lasts two minutes, and the challenge is to earn points through merges before time runs out or the cauldron overflows.
How to play this watermelon-style game
- Start a brew. Open Cauldron Drop and press Play for the standard rules. Change rules lets you start a different challenge.
- Aim before you drop. Move the mouse over the cauldron and click, or drag a finger and lift it to release the material. With a keyboard, use Left and Right or A and D to aim, then Space, Enter or Down to drop.
- Bring twins into contact. Only matching materials merge. Two Dew make a Spark; two Spark make a Pebble. A fresh material can touch its twin and start another merge in the same chain.
- Read Next. The preview shows the piece after the one in your hand. Only Dew, Spark, Pebble, Leaf and Mushroom are dropped directly; larger materials must be made by merging.
- Watch the dashed rim. Landed pieces above it for two seconds end a standard brew early. A piece that is still falling does not count, and clearing the rim resets that countdown.
- Keep practicing. At the result screen, Play again repeats that day's starting sequence. Keep brewing continues without a clock; an overflow then empties the practice cauldron instead of ending play.
Only merges score points. A standard brew awards one star at 300 points, two at 700 and three at 1100. Practice does not change your best score.
Fruit merge order: this version's alchemy material table
Fruit names and the number of stages depend on the game you are playing. For Cauldron Drop, use the exact ten-stage chain below instead of a fruit chart. Each row is larger than the one before it. Combine two of a material to make the next row.
| Level | Material | Points |
|---|---|---|
| 1 | Dew | 0 |
| 2 | Spark | 2 |
| 3 | Pebble | 6 |
| 4 | Leaf | 12 |
| 5 | Mushroom | 20 |
| 6 | Crystal | 30 |
| 7 | Moon | 42 |
| 8 | Sun | 56 |
| 9 | Star | 72 |
| 10 | Philosopher's Stone | 90 |
Dew is the starting material, so it has no creation points. Two Philosopher's Stones that touch vanish together for 110 points; there is no extra material after them. In Crystal Week, merges that create Crystal or a larger material score double the standard points shown above.
Tips to keep the pieces inside the box
In Cauldron Drop, staying inside the box means keeping the settled pile below the dashed rim. Use these placement habits to leave room for the next few pieces:
- Keep the top of the pile low and broad. Repeatedly dropping into one narrow column builds a tower near the rim. Use lower spaces when they leave a route to a matching piece.
- Keep twins within reach. A Pebble buried under several different materials is hard to match. Before covering a piece, check whether your current or next drop can reach it.
- Plan around the next piece as well as this one. A quick merge may seal the space needed by the next Mushroom. Look at Next and leave a landing place for it.
- Watch the roll after a drop. Round materials can slide off a slope. Aim toward a twin's side when a straight drop would perch on top of an unrelated piece, and allow a chain to settle before committing another drop.
- Make space near the rim first. When the stack is high, look for an accessible small pair that can clear the top. Chasing a distant large merge can add a blocking piece where you have the least room.
- Use Gentle Brew to learn recovery. It extends the overflow grace period from two to four seconds. Double Preview instead shows the next two materials, which helps you practice planning placements.
A useful practice goal: replay the same day's brew and change the placement that first split a matching pair. The drop sequence repeats, so you can compare the effect of your decisions. These habits improve your chances; they do not guarantee a clear cauldron.
Frequently asked questions
Can I play this watermelon game for free without a download?
Yes. Cauldron Drop is free to play in your browser on a phone or computer, with no download or account needed. Open the game and press Play to start a brew.
What is the fruit merge order in Cauldron Drop?
It uses ten alchemy materials instead of fruit: Dew, Spark, Pebble, Leaf, Mushroom, Crystal, Moon, Sun, Star and Philosopher's Stone. Two matching materials touching make the next one; two final Stones vanish together.
Why did my game end before the timer ran out?
In a standard brew, landed materials that stay above the dashed rim line for two seconds cause an overflow. A material still falling does not count. Clearing the rim resets the countdown; Gentle Brew gives you four seconds.
Can I play without the two-minute timer?
Yes. Choose Keep brewing on the result screen to continue without a clock. If the practice cauldron overflows, it empties so you can carry on. Practice does not change your best score.
What happens when I merge two of the largest materials?
Two Philosopher's Stones that touch disappear together for 110 points in a standard brew. There is no eleventh material in Cauldron Drop.
Does every restart give me different pieces?
No. The drop sequence is seeded by the UTC date. Everyone gets the same sequence that day, and Play again restarts it from the beginning, so you can try a different placement plan.
Try the alchemy version
Take the merge order into a fresh brew. Start by keeping Dew and Spark pairs accessible, then make room for the larger materials as the pile grows.
