Merge Drop is a physics game about dropping balls and combining them. When two balls of the same size touch, they merge into the next size up and score points. The balls obey gravity, roll, and pile — so where you place each one matters. Keep growing bigger balls, but never let a pile settle above the top line.
The board is a tall bin, open at the top. A faint danger line sits near the top, and a NEXT badge shows the ball you'll drop now plus the two after it. Your job is simple to state and hard to master: build the largest balls you can without overflowing.
Every merge is worth points, and bigger merges are worth dramatically more. The score from a merge grows with the size of the ball it creates — roughly with the square of its tier — so a single high-tier merge can outscore a long string of tiny ones. That math is the whole reason the game rewards patience: grinding the two smallest balls together over and over earns far less than nursing the board up to the larger tiers.
Two extra layers sit on top of the base score:
The top tier pops. When you merge two of the largest balls, they don't grow any further. Instead they pop and vanish together for a large score burst — and that pop is itself eligible for the cascade multiplier. Reaching the top tier is therefore both the headline achievement and your best way to clear a crowded board, since the pop frees up the space those two giants were occupying.
Merge Drop rewards a plan more than fast hands. A few habits separate a short run from a long one.
Keep your largest balls low and to one side, and let smaller balls collect on top of them. When you can, merge smaller balls downward onto a same-size partner so the growing ball sinks rather than rises. The worst thing you can do is strand a big ball under a heap of mismatched small ones — it can't merge, and it eats vertical space you can't get back.
The smallest sizes are your tools for filling gaps and triggering chains, but only if you can reach them. Don't bury a lone small ball in a corner where its future partner can never touch it. Leave a clear lane to any unpaired ball so the next matching drop can close the deal.
The most satisfying — and highest-scoring — moments come from setting up a row of same-size balls so that one merge sets off the next. Line up two pairs of equal size next to each other; merging the first pair creates a ball that's now equal to its neighbor, which merges again, and so on. Reading the NEXT preview lets you stage these on the drop before you need them.
Treat height as your real resource. Dedicate one side as a "release valve" — keep it lower than the rest so you always have somewhere safe to drop a ball you can't immediately place. If the pile creeps toward the line, stop adding fuel: look for an existing same-size pair you can complete to drop the whole stack a level, instead of dropping a fresh ball that adds height.
Merge Drop has two modes, and they're built for different goals.
Because Ranked keeps your best, the smart loop is to play once to read the day's sequence, then retry to improve. The first run teaches you where the early balls want to go; later runs let you place them deliberately. Step away mid-run and your daily board is paused — come back and pick up where you left off, on the same worldwide sequence.
Two balls of the exact same size that touch combine into one ball of the next size up and score points. Different sizes never merge — they simply rest against each other until a matching ball arrives.
Build toward the larger tiers, since a merge's value rises sharply with the size it creates. Then set up cascades — one merge that immediately triggers the next — because each chained step multiplies the score. The top-tier pop is the biggest single payout.
The largest of the seven sizes doesn't grow further. Merging two of them pops both for a large score burst and clears that space, which is the cleanest way to relieve a crowded board.
When a ball settles above the top danger line and stays there briefly. A ball that bounces past the line and falls back is fine — it's a resting, over-the-line pile that ends the run, so keep height under control by merging.
Yes. Ranked keeps your best score for the day, so you can replay the same worldwide board as many times as you want and only your top result counts. Free play is unlimited too, with its own best score kept.
