The beauty of digital guides is the ability to keep them up to date with any DLC, patches or strategy improvements. So we'll list any improvements or changes we make to the guide here, so you can tell when it was last updated.
Last Updated:23rd December 2013
* Once again based on user feedback we've added a new Turbo Dryer No Item strategy for Heroic difficulty. As of the 1.5 update, iPhone and iPod players can now use the extra towers (such as the Gatling Tower), so this strategy works across all versions.
* Based on user feeback, we've added an Endless Mode strategy that helps you to earn 5 million + points and reach round 201+ on Heroic difficulty with zero leaks. This allows you to unlock multiple cards in a single playthrough and offers scope for a massive high score.
* Achievement/Card strategies page updated to reflect new Endless Mode strategy.
28th March Changes
* Improved the 'Turbo Dryer' 3-stars strategy based on user feedback, no longer requires the use of a Machine Gun Tower, so it now works on all versions. 3-stars now also easier to get on this level with the new strategy.
