Trivia

 * It's possible to spend all the money given and lose all the lives in the Bloons Tower Defense 4. The amount of money given is not infinite and if 35 B.F.B.s escape, all the lives will be lost.
 * In Bloons Tower Defense 5, the player's lives and cash amounts are represented by a dash, showing that they are unlimited.
 * In Bloons Tower Defense 4, it says that the player is playing Round 1 and if the player loses, it will say "You ran out of lives on Round 1".
 * Sandbox Mode is not featured on mobile versions of Bloons Tower Defense 4.
 * Sandbox Mode was considered an Easter egg on early versions in Bloons Tower Defense 5 Mobile and was removed in version 1.1, but it reappeared in version 1.2 along with the release of the new track, Brick Wall; the player must make a one-time payment of 1500 to unlock and use Sandbox Mode in Bloons TD 5 iOS.
 * It is possible to achieve high theoretical rounds too; the next "round" will start when the final bloon on the map is popped. Thus, bloons will move at high speeds at extremely high "rounds".
 * This glitch has been fixed, since even if you make 150 "rounds", the bloons don't get any faster or stronger. Also super ceramics don't seem to appear.
 * You can know the "round" number by achieving tier 3 of spike factory specialty building, when the free road spikes are not used, or the free dart monkeys every 10 rounds.
 * A line of bloons cannot be made in the iOS version.
 * Sometimes, when you hold down the hotkey for a bloon to make a line of that bloon, the line will end, or the line will be broken.
 * In BTD5, Banana Farms in Sandbox Mode only start producing cash when bloons appear. When bloons stop appearing, they stop producing cash.
