Chute Foundry: Marble Builder

Build a pegboard of chutes, curves, ramps and boosters so that every marble lands in its matching cup. Each level has hoppers at the top, cups at the bottom, and bricks, scrap pits and glue strips in the way. Pick a piece from your tray, drop it on the board, rotate it or flip it where the piece allows, and press Run to watch the marbles drop. The simulation uses exact whole-number maths, so the same board gives the same run every time on your phone. Change one piece and only its effect changes. Stars count the pieces you take from the tray, so a board that uses fewer pieces earns more stars. There are 100 levels in five workshops of 20. Each workshop adds new pieces: trampolines and bumpers, booster magnets and one-way gates, colour splitters, and finally all of them together. A tutorial card explains each new piece the first time it appears, with a short looping demonstration. Levels unlock in order. The first three levels of a workshop are open, and each solved level opens the next one. A new workshop opens when 15 levels of the one before are solved. There is no timer and no energy limit. Your board is saved after every change, so you can close the game and pick up where you left off. Stuck on a level? Ghost preview draws the path of the first marble so you can see where the run goes wrong. You start with three Ghost Preview tokens and earn one more for every 10 levels you solve for the first time. A rewarded video also gives one preview per level when you have no tokens, and another rewarded video can add one extra piece of a type already in the level's tray. Rewarded offers are always optional and labelled. The game contains ads and offers in-app purchases. An interstitial ad called Run break can appear only when you leave a result screen after a solved level. It never appears before your fourth solved level, never more than once every two solved levels, never less than 120 seconds apart, and never during play or after a failed run. Remove Ads is a one-time purchase that removes Run break ads; rewarded offers remain. Ghost Preview ×10 is a consumable pack that adds ten Ghost Preview tokens. The game is for players aged 13 and over. It plays offline. The internet is used only for ads and for purchases through Google Play.
