Blue Hole is a is a wildly addictive high score game that sends you on a suicide mission toward the bottom of the ocean. Your goal? To sink as far as possible while collecting coins and avoiding dangers like mines, sharks, and ink-squirting electric sea-beasts.
Like all high score games worth their salt, the gameplay in Blue Hole is extremely easy to pick up but tough to master. The only control input you have is the ability to steer your submarine left and right, and to apply the brakes. Your brakes wear out quickly, however, and require time to regenerate, so you’ll have to rely on your reflexes to avoid catastrophe most of the time.
A string of coins guides you downward into the darkening depths. Following it usually leads you where you need to go to avoid colliding with ocean rocks and mines, but not always. Also, living sea creatures can and will cross the path of the coins, so you have to keep your eyes open to avoid them. As you reach new depths, you’ll keep speeding up and finding new enemies, which makes the game tougher but also more exciting.
The environment remains the same every time you play, so you’ll tend to get farther with each attempt. When you accumulate 2,000 and 10,000 coins, you can upgrade to better submarines that move quicker and can withstand more damage. We wish there were more than two additional vehicles, because you can unlock them both in under an hour, leaving the OpenFeint leaderboards and achievements the only reason to keep coming back.
Each play session of Blue Hole lasts only a few minutes, so even if you just pick it up when you have a moment of time to spare, it’ll give you a quick shot of gaming goodness.
