How to play
- Tap a square to place the chosen ramp. A ramp pointing right sends the marble one square to the right, and a ramp pointing left sends it one square to the left. After that it falls on.
- You only have the ramps shown in your hand. Tap a ramp you placed to pick it up again.
- Press Drop the marble to test your layout. The squares it visited light up, and a message says what stopped it.
- Walls stop the marble. Get it onto the flag square on the bottom row to solve the puzzle. A new daily puzzle arrives every day.
Controls: mouse or touch. Made by CalcoTools.
Tips and strategy
- Work backwards from the flag: which column must the marble be in just above it?
- Count how far sideways the marble needs to travel from the arrow to the flag column. That is how many net ramp moves you need.
- A ramp only works when the marble falls through its square, so each ramp must sit in the marble's column.
- Use the lit trail after a failed drop to see where the marble went wrong.
FAQ
- Is there always a solution?
- Yes. Every level is built from a working route, and the game checks yours by dropping the marble.
- Can ramps chain?
- Yes. If a ramp sends the marble onto a square that holds another ramp, that ramp acts at once.
- What counts as a move?
- Placing, picking up and dropping each count once. Fewer moves is better.
