Dropbound
Read full descriptionHide full description
Set the switches. Press DROP. Rescue every critter, in the right order. Dropbound is a puzzle played in glass pipes. The ball waits at the top behind a gate. Below it, one pipe splits at switches into a tangle that weaves over and under itself, and critters sit trapped in bubbles under its exits. Set the route, then drop. One ball frees one critter. Free them all before your balls run out. HOW TO PLAY - Tap a switch to choose which way it sends the ball - Press DROP when you are ready. There is no timer and nothing to time - Reach a critter and its bubble pops. End anywhere else and the ball is spent WHO GOES FIRST? Every critter is on the board from the start, and you choose the order. From board 16, flip switches can't be tapped: every one of them turns at the end of every drop, wherever the ball went. So each rescue changes which critters you can reach next. Free the wrong one first and you may need your spare ball. Every board can be cleared with one ball per critter. 300 BOARDS One switch on board 1, seven exits later on. Blocked pipes from board 11: two pipes to the same critter, and a cork in one of them. Two ways into one critter from board 21. Teleports from board 31: drop into the hole and come out of a bent pipe somewhere else. THREE STARS Every board has three to earn: cleared, first try, and fewest balls. DAILY BOARD One board a day, the same for every player. One try. Keep your streak and share your result. CRITTERS, MISSIONS AND BALLS Six species to rescue and collect, and golden critters to find. Three missions at a time: finish the set to level up and earn a new ball. NO LIVES, NO TIMER Out of balls? Try again straight away. Coins are earned by clearing boards and buy an extra ball when you want one. No accounts. Plays offline. No gambling and no in-app purchases. Anonymous analytics you can switch off. Download Dropbound and rescue your first critter today.
