Droptide: Drop Merge Puzzle
Bioluminescent fusion puzzle
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Auto Drop is here: one switch, and the water lets go of a creature every quarter second. The aim is still yours. Free for one run, in every mode you play.
Droptide is a drop-and-merge puzzle set in a bioluminescent tidepool.
Drag to aim. Let go. Two creatures of the same kind touch and fuse into something larger — a Spark becomes a Drifter, a Drifter a Bloom, on up through nine tiers to the Leviathan at the end of the chain. The pile grows as you play. Keep it below the line.
That is the whole rule. Everything after it is what the water does with it.
THREE WAYS TO PLAY
Tide — no clock at all. Take as long as you like over every drop.
Riptide — two and a half seconds a creature, then the water takes it, aimed or not.
Auto — nobody plays. The pool blooms on its own, at half speed or triple, and you watch.
Same gravity, same current, same danger line in all three. The only thing that changes between them is who lets go of the creature, and when.
ONE WAY BACK
Merge a Wraith and you bank a bomb. It is not a tool: the only moment you can spend it is the one where the run would otherwise have ended. The water slows to a crawl and you get a single tap — take the creature holding everything up, and the column collapses back below the line.
IT DOES NOT LOOK LIKE THE OTHERS
Most games in this genre draw the circles they simulate. Droptide draws neither. Underneath, the physics is rigid bodies, because rigid bodies stack and stacking is the game. Over the top is a liquid field: creatures pool into one another where they touch, and every merge stretches a glowing neck between the two halves that closes a beat before the new creature exists.
There is not an image file in the app. Caustics, god rays, marine snow, the glass of the vessel and the light coming off a fresh Leviathan are all drawn from scratch, every frame.
AND IT DOES NOT SOUND LIKE THEM
Nothing is a recording. Every note is generated as you play — struck bells in one minor pentatonic key, the creature's tier choosing the register, the melody wandering so that no two chains arrive the same way. A long combo climbs the scale instead of just getting louder. Underneath all of it, a slow three-oscillator swell. Headphones are the way to play it.
FOUR PALETTES
Tidepool, the original chain. Voltage, hues pushed apart so that no two tiers read alike. Coralline, warm reef sand running down to cold water. Silverpoint, no hue at all — tier is pure brightness, dim slate to white.
GAME CENTER
Leaderboards for timed and untimed play, kept separate, because the same number means something different when a clock is letting go of the creature for you. Ten achievements besides, from your first Lantern to a twelve-thousand-point Deluge. Auto runs are for watching: they score nothing and submit nothing.
QUIETLY BUILT
No ads. No account, no sign-up, no tracking. It runs with the airplane mode on — the whole game is in the app, and nothing is streamed, fetched or downloaded while you play.
One hand, one thumb, and any length of time between thirty seconds and a long bus ride.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
AUTO DROP — NEW
• A new switch in the corner of the screen, next to the settings cog.
• It is off when a run starts. Tap it to turn it on, tap it again to turn it off.
• While it is on, a creature drops on its own every quarter of a second.
• You still aim. Only the timing is taken off you.
• It works in Tide, Riptide and Undertow.
• The first time you press it is free and lasts that run. After that it is part of the one purchase.
AUTO IS NOW CALLED ZEN
• Same mode, same leaderboard, same speed chip.
• Only the name changed. Auto Drop needed the word.
STATISTICS — NEW
• A new screen: Settings, then Statistics.
• Your best score in all four modes, side by side.
• Lifetime totals: runs played, merges, time played, deepest creature, longest chain, and how many times a bomb saved a run.
• These were already being counted. Now you can see them.
THE END OF A RUN
• The card now shows three numbers under your score: merges, longest chain, and how long the run lasted.
• Play Again is the first button. It replays the mode you were on.
• Change Mode goes back to the mode list.
TWO LEVIATHANS
• Before: a second Leviathan could not merge with anything, so it blocked the vessel for the rest of the run.
• Now: two Leviathans cancel each other out, clear the space, and score 900 points.
ALSO
• New launch screen.
• Still offline. Still no ads, no account.
