Robogoyo is a engrossing puzzle involving a simple series of rings and a long oval pin. Using the minimal number of locking and unlocking moves, weave the oval pin through all the rings in the shortest possible time to solve the puzzle. Despite just 8 rings and only two possible moves at any time, you will have to think hard to plan your sequence of moves. Engage your mind and challenge others too!

The Robogoyo Game App was developed from a unique 3D puzzle toy, a gift with truly ancient origins. It has delighted generations of players, both children and adults, well before the age of smartphones and even paper. The puzzle itself builds concentration and problem solving skills by forcing you work out the quickest and most logical order of moves. Enjoy solving the puzzle with 8 rings for free - simply download and get started on solving it. Once you master this, you can pay and play the more challenging versions with more rings too! Have fun!

We start the game with the oval piece being separate from the interconnected rings. Let’s understand the rules of locking. The rings are interconnected with one ring standing free. Number the free ring 1 and the other rings in order from 2 through 8. Now, Ring #1 can be locked and unlocked at any given point of time in the game. Any higher numbered ring can be locked or unlocked if the previous ring is locked and all lower numbered rings are unlocked. For example, to lock ring #5, we need to have ring #4 locked and all lower rings (#1, #2, #3) unlocked. As another example, if rings #6 and #7 are locked while #1, #2, #3, #4 and #5 are unlocked, and then at this point, #7 ring can be unlocked.

With only two moves (locking or unlocking) possible at any given time, it's up to you to figure out the correct order of moves. You will have to make exactly the right movement in each of the steps to finish the puzzle in the shortest possible manner. Any mistake during the game will increase the number of moves, as the wrong steps have to be retraced before the player can continue on the right sequence of moves. Once all rings are in locked position, the same sequence has to be reversed to make the oval piece free.

The underlying algorithm dictates that for each additional ring that need to be locked, the number of movements (locking or unlocking) doubles. 8 rings require 170 moves and 9 rings take 341 moves! Are you ready for the ultimate brain teaser?
