Free the coin puzzles are always interesting and fascinating puzzles. They usually have a hidden mechanism that you need to figure out in order to free the coin trapped inside. Rizal is a great example of such puzzle designed by Rex Rossano Perez from the Philippines.

This is a tiny puzzle, but don't judge it by its size. It has an elegant solution that will surely satisfy your puzzle needs. Measuring only 6.8cm x 5.7cm (2.7" x 2.25) and made in acrylic, it's a sturdy puzzle that will withstand the most frustrating puzzlers - Although its difficulty is not that hard. Inside there's a 1 Piso coin resting on a sliding platform that doesn't always move like you'd expect. It's here that the hidden mechanism comes into play and some outside-the-box thinking is needed.

The sliding mechanism is a clever addition to the design and even though it's not that difficult to figure it out, it's certainly an enjoyable experience. Another interesting aspect of the puzzle is the multi-layer platform that adds an extra complexity to the design and mechanism.

Solving the puzzle did take me about 10 minutes, so it's definitely not a straightforward solution. When the coin disappears from view, you'll be left with just the sound the puzzles makes when the platform moves - or tries to move. You'll have a nice "a-ha!" moment when the coin falls from the opening at the bottom. It's not as difficult to return the coin to its original position, but it can still be challenging if you haven't memorized how exactly the mechanism works.
