A drawn ink line guides a red drop into a test tube

Easy to start, satisfying to master

Every level is a small physics experiment. There is rarely only one answer, and finding the line that uses the least ink is half the fun.

1

Draw

Sketch a ramp, a bridge, a funnel or a wall with your finger. Ink is limited, so every stroke counts.

2

Drop

Gravity takes over. Drops bounce, roll and slide along your line, and merge when they touch.

3

Route

Fill each tube with the right color. Save ink, finish clean and beat the challenge to earn all three stars.

Inside the lab

150 levels across 9 labs. The puzzles get trickier lab by lab, until the Master Lab throws every gadget at you at once.

Mix colors

Red and blue make purple, add yellow for orange. Discover every reaction and fill your Formula Book.

Lab gadgets

Portals, heaters, fans, gravity fields, filters and sticky pads change how every drop behaves.

Three stars

Finish the level, spend less ink and complete a special challenge: no erasing, fewer lines or beat the clock.

Make it yours

Collect inks, drop skins, 9 lab themes and win effects.

Play offline

No internet needed to solve puzzles. Short levels for a coffee break, a commute or a flight.

Color-blind friendly

Turn on shapes that mark every color. Available in 13 languages.

In his memory

Why this game exists

My grandfather spent his life working with plants and built a small lab in his village in the 1980s. Drop & Route is my way of carrying his work forward. One of its labs is named after him.
