OilRhythm vs Boltfall

Draw a line, and the oil flows down it. One finger, one gesture. Where you want the oil to end up is what makes the four ways to play. - Machine A puzzle of contraptions: land the oil in the vessels. Toppling boards, tipping buckets, cups that overflow, pulleys, lifts, a big wheel. Draw lines to drive the machine and deliver as many drops as the stage asks for. Slipping past the machine still clears it; sending the drops through it earns the star. NORMAL: 125 stages HARD: 125 stages In HARD you also draw blue gimmick lines that hold up boards and machines. Levers, weighing trays, shuttles, seamed boards, listening gates, clutches, tune locks and cutting blades. Each new part is shown with a short demo the first time it appears. - Time A puzzle where rushing loses. You have to reach the goal slower than the target time. Send the oil the long way round, make it bounce, let it linger. Designing that path is the puzzle. 260 stages. - Music Oil traces your lines and notes ring out. The longer the line, the higher the note. You design lines so the oil plays a given melody, with duets and stages that layer a front and a back. Choose from 21 instruments. - Make Workshop Build a machine of your own. Place the vessel, the ledges and twelve kinds of parts, then decide how many drops fall and how many must land. You can try your own line right there to see that it can be solved. Garden A board with no goal and no timer, made for watching. Place the gimmicks you have earned, draw a line, and the oil keeps flowing forever. Background, oil look and falling pace are saved per garden, so each one becomes its own scene. Compose Place notes to write a tune and play it as a stage. Export what you write as a code and share it. - Something to collect Watch the oil in Garden or timer mode and now and then a drop falls wearing a look you have never seen. Gems, neon, sea creatures, planets, fruit and more, 71 in all. Each family also unlocks scenery, 13 backgrounds in total. The bear, the cat, the chick - your Friends join you one by one, at each milestone of Machine. --- In-app purchases (one-time, no subscription) Premium Keep as many gardens and machines as you like / all 21 instruments / unlimited songs and exports / no ads Remove Ads Removes the ads shown after clearing.

Every plate hangs on its bolts. Unscrew them in the right order and the steel comes crashing down. Sort colours into a three-slot holder — three alike clears it, one wrong bolt jams it. Easy to start, genuinely tricky to master, and satisfying every single level. HOW IT PLAYS • Tap a bolt to unscrew it. Free every bolt on a plate and the plate falls away. • The holder has three slots. Three bolts of one colour clear a set. Mix colours and you jam. • Deep bolts need several full turns — commit to one and it reserves a slot. • Covered bolts hide under layered steel. Drop the plate above to reach them. WHY YOU'LL STAY • 150 hand-tuned levels across six workshops, from Toolbench to Foundry • A real difficulty curve: think two moves ahead, not just match colours • Undo, hints and boosters when you're stuck — never pay-to-pass • Short levels, one-hand play, works offline • Colour-blind friendly: every colour has its own head shape No forced video ads. Ads only play when you ask for a bonus.
