iFanzine’s digital prize-bag is bursting at the seams this week with promo codes for smash-hit iPhone and iPad games like Shake Spears! HD and Sonic & SEGA All-Stars Racing as well as must-have indie titles Alice in Labyrinth, Necta Collecta and The Greedy Sponge!

Shake Spears! HD: “Not only the best jousting game ever but also one of the greatest and most memorable iOS games in its price range”, according to Sean’s glowing, 5-star review. Recommendations don’t come much higher than that! Courtesy of the kind folks at Alawar Entertainment Inc, we’ve got 1 copy of the stunning iPad edition of Shake Spears! to give away.

Sonic & SEGA All-Stars Racing: You guys enjoyed our Sonic & SEGA All-Stars Racing contest so much last time around we decided to give away the game again! Featuring a roster of iconic SEGA characters, 15 topsy-turvy tracks inspired by hit games and, perhaps best of all, action-packed party play either locally through bluetooth or online, Sonic & SEGA All-Stars Racing truly is fun from start to finish line! Thanks to SEGA, we’ve got 1 code up for grabs.

The Greedy Sponge: If you think a cross between Match-3 (actually, make that “Match-5″) and Tetris sounds grand, this one should nicely fill your gaming gullet.” You can check out our full review of The Greedy Sponge here or simply enter to win 1 code courtesy of Ivica Aracic.

Necta Collecta: This cute and charming puzzle game has been getting some impressively positive buzz so far. Highlights include unique gameplay, a wealth of different modes, leaderboards and much, much more. 4 codes must be won thanks to Michael Buettner.

Alice in Labyrinth: A surreal adventure that sees the player solving a series of puzzles and riddles in order to escape the clutches of the Queen and make it out of a nightmarish Wonderland in one piece. Thanks to Twinkle Lab and our good friends at AppsJP.com, we’ve got 7 codes to give away!
