Round 38 (pre-BTD6)

Round 38 is a round first introduced in Bloons TD 1, and has reappeared since the franchise's debut. There are many versions of Round 38 depending on the game. The general trend for Round 38 is the mixture of multiple bloon sends followed by a few strong bloons.

Bloons TD 5 features Regrow Pinks instead of normal Pinks and sends 4 Rainbow Bloons instead of 2 finely spaced Ceramic Bloons.

Tips

 * Sniper Monkeys are a helpful assistance for beating the Ceramics, given their high-damage single-target capabilities. On the other hand, relying on Snipers for popping Leads will be a trouble on this round, given that Leads and Zebras will intermingle on the same round.
 * Spike Factory may be useful for this round if worried about leaking some remains of the Ceramics. Don't rely on Spike Factories on this round, but rather use them as a last line of defense.
 * Spiked Ball Factory is powerful against this round if using Spike Factories as a major form of popping power, given its high Ceramic damage, high pierce. Still keep the main defense focused on the frontline direct attackers, as a single Spiked Balls can't simply solo everything on this round.
 * Use of cheap slowdowns are effective for this round. Permafrost is among the cheapest pure slowdowns, next to lower-level Glue Gunners.
 * Freezing is useful for this round to deal with Ceramics, but this will not deal with the Whites or Zebras on this round.
