Nintendo has lifted the curtain on the first 5 titles available on the Nintendo DSi Shop downloadable software store when its new DSi handheld launches April 5.

All developed by Nintendo, the titles include a new WarioWare game apparently with a baby-upsetting minigame, a pretty undersea puzzle game, birds tonguing beans, more Brain Age and a smattering of wonderous magical illusions--don't call them tricks.

Nintendo offers these brief explanations:

WarioWare: Snapped! - Using the built-in Nintendo DSi camera, this outrageous title puts players right at the center of fast-paced mini-games, challenging them to race the clock and get a peek at Wario's photo album.

Bird & Beans - Using an elastic tongue, players must scramble to collect falling beans. The harder a bean is to catch, the more points it's worth.

Brain Age Express: Math - In this math-focused edition of the popular Brain Age series, players can enjoy a mix of new and familiar training exercises. A new Themes mode also lets Nintendo DSi users experiment with images and voice recordings in fun, unusual ways.

Master of Illusion Express: Funny Face - This game uses your Nintendo DSi as a prop in a card trick. Draw a face on the touch screen and astound your audience as the face tells them which playing card they picked.

Art Style: AQUIA - The newest addition to the eye-popping Art Style series, this mesmerizing underwater puzzle game challenges players to help a scuba diver reach the ocean floor by matching a series of colored blocks.

Software on the DSi Shop is paid for with Nintendo DSi points--which are not interchangeable with Wii Shop Channel points. You can pick up a nifty 1000 DSi points for free in the US if you buy a new DSi and go online within the first six months.

Already launched in Japan, and arriving in Europe on Friday and North America on Sunday, the Nintendo DSi marks Nintendo's third revision to the portable hardware.

Priced at $179.99, it packs bigger screens and a slimmer profile than previous iterations, along with two cameras and the ability to downloadable games. However, as part of that slimming, the DSi has lost its cartridge slot for Game Boy Advance titles.
