When indie developer Zach Gage was first told about a video game that combined Tetris and Boggle, he had a very specific idea of how the game would play.
But after seeing that the prototype of Puzzlejuice played differently, he created—with the developer's permission—the version he imagined as SpellTower.
Gage's game eventually released prior to the game that inspired it.

SpellTower released for the iPad tablet computer on November 17, 2011.
A month later, Gage added support for iPhone and iPod Touch, and Game Center achievements.
In 2012, Gage added local multiplayer support over Bluetooth in a new battle game mode.
Gage later released versions for OS X (July 25, 2012) and Android (March 7, 2013).
The Android release is identical apart from the omission of word lookup.
It also supports local Wi-Fi multiplayer and high score competition via Scoreloop.

Gage and developer Jack Schlesinger rebuilt SpellTower from scratch to better accommodate changes made since its original release.
The new version, SpellTower+, has a revised look, a new soundtrack, iCloud backup, and new game modes.
