In the Resources page, I link both an HTML5 version and a flash version of Civiballs. These versions have a physics discrepancy that make tricks incompatible with each other. The plainest way to see this is China 6. The default strategy is to cut the red ball into the crossbow, then while that is settling cut the yellow ball. Once red is settled, shoot the red ball then cut the green to drop it into the green vase. The red then rolls across the top, falls down onto yellow, sending yellow and red into their own vases ending the level. This default strategy works on the Flash version of the game, but in the HTML5 version, yellow doesn't land in the vase unless it bounces into the red ball on its way down.

This manifests into some levels that are much faster, for example Egypt 3 has a strategy in Flash where you cut red and green immediately after each other and red bounces off the cannon into the vase, meaning you only wait for a single cannon shot rather than the two required in the HTML5 version. Similar improvements are found in Egypt 7, Greece 7, China 7 and 10, and likely more. I plan on making IL runs to demonstrate these differences in the coming months.

For this reason, I request a platform indicator to distinguish between HTML5 and Flash. I think these discrepancies are too small to have a separate leaderboard, but significant enough to note. Thoughts?

Civiballs China 8 has a 9 second time save called the short Johnson, named after it's discoverer, demonstrated here: There is a simpler version of the trick dubbed the long Johnson where the top-left green ball is hooked straight into the vase while the middle-right green ball is hit into the crossbow as shown in the short Johnson. This version saves 6 seconds over the vanilla route and is much easier to perform.
