Beneath The Lighthouse is a serene puzzle action game that takes you on a journey with a boy in search of his lost Grandpa. The game is optimized for iPhone 5, iPad 3, iPad mini 2, and iPod Touch 5G or newer, although it can be played on older devices with a slightly less smooth experience.

In the free version of the game, advertising is used to monetize the experience. There are no coins, gems, boosters, or timers to pay for, but there is a lives system that adds a fair challenge to the gameplay. If you prefer an ad-free experience without the lives system, you can unlock the premium version with a single in-app purchase.

It's worth noting that the premium version removes third-party ads but still includes cross-promotion for other Nitrome games. Overall, Beneath The Lighthouse offers a captivating and immersive puzzle action experience that will keep you entertained as you unravel the mystery beneath the lighthouse.
