"Finish a game with exactly half your starting lives and half your starting cash."

- Official BTD6 description

Snap of Your Fingers is an achievement in BTD6. It is achieved by finishing a game with exactly half starting lives and half starting cash. Earning this achievement will reward 2 random Tier-1 Instamonkeys, 2 random Tier-2 Instamonkeys, and 1 random Tier-3 Instamonkey. The amount of money at the end of the game includes the money from the last bloon popped and excludes the reward at the end of the round. As an example, with the base starting cash of $650 and easy mode (40 rounds), the target is $325. The player should end with $325 including the $381 made during round 40 and excluding the end-of-round reward of $140.

Tips

 * It is easier to finish this achievement on Deflation Mode.
 * Monkey Knowledge affects calculations; it may be simpler to start without Bonus Cash and the various discount MK.
 * Mana Shield lives are not included in the half lives count.

With Heroes

Turn off Monkey Knowledge (and Double Cash Mode, if applicable), select Striker Jones and start a Deflation game on Logs. This strategy only requires attention on round 33 and 36. Place Striker Jones, a 2-3-0 Bomb Shooter (with strong target priority), and a 2-2-0 Wizard Monkey in the square to the left of the water. Place a 4-0-2 Monkey Sub (on Submerge) anywhere in the water. This will get you to $10000. On Round 33, let the Reactor kill exactly 3 Camo Yellows, then unsubmerge it. Let the rest of the Camo Yellows leak, bringing you down to 160 lives, then submerge again to kill the Camo Reds. On Round 36, unsubmerge the Reactor for the entire round, letting the 20 Camo Greens bring you to exactly 100 lives. Submerge the sub and wait out the rest of the game.

Turn off Monkey Knowledge (and Double Cash Mode, if applicable), select Captain Churchill and start the game on Logs on Deflation Mode. Place Captain Churchill in the square to the left of the water. Place a 2-0-4 Tack Shooter in the square beneath the water. Place a 4-0-0 Monkey Sub (on Submerge) and a 0-1-1 Monkey Buccaneer, anywhere in the water. This will get you to $10000. On Round 33, let the Reactor kill exactly 3 Camo Yellows, then unsubmerge it. Let the rest of the Camo Yellows leak, bringing you down to 160 lives, then submerge again to kill the Camo Reds. On Round 36, unsubmerge the Reactor for the entire round, letting the 20 Camo Greens bring you to exactly 100 lives. Submerge the sub and wait out the rest of the game.

Turn off Monkey Knowledge (and Double Cash Mode, if applicable), select Adora and start the game on Logs on Deflation Mode. Place Adora, a 4-0-0 Alchemist, a 0-2-0 Boomerang Monkey, and either a 1-0-0 Druid/0-1-0 Druid, in the square to the left of the water. Place a 4-2-0 Monkey Sub (on Submerge) anywhere in the water. This will get you to $10000. On Round 33, let the Reactor kill exactly 3 Camo Yellows, then unsubmerge it. Let the rest of the Camo Yellows leak, bringing you down to 160 lives, then submerge again to kill the Camo Reds. On Round 36, unsubmerge the Reactor for the entire round, letting the 20 Camo Greens bring you to exactly 100 lives. Submerge the sub and wait out the rest of the game. Remember to use Adora's The Long Arm of Light Ability for the moabs. [Current as of Version 29.3]

Turn off Monkey Knowledge (and Double Cash Mode, if applicable), select Adora and start the game on Logs on Deflation Mode. Place Adora, a 0-3-2 Boomerang Monkey set to strong, a 3-0-0 Alchemist adjacent to it, a 0-0-0 Wizard Monkey and a 4-0-2 Monkey Sub. On Round 33, let the Reactor kill exactly 3 Camo Yellows, then unsubmerge it. Let the rest of the Camo Yellows leak, bringing you down to 160 lives, then submerge again to kill the Camo Reds.

Without Heroes

Turn off Monkey Knowledge (and Double Cash Mode, if applicable) and start the game on Logs on Deflation Mode. Place a 3-2-0 Heli Pilot, a 4-0-0 Alchemist near the Heli, a 0-0-0 Monkey Buccaneer, and a 0-0-0 Monkey Sub (Location doesn't matter, for this is just to reach exactly 10,000 cash, however placing them near the track is beneficial). Carefully leak exactly 100 lives, drawing the Heli Pilot away from the track until the amount of lives reaches 100. Then, set the Heli Pilot on pursuit. If done correctly, the game should be completed with exactly 100 lives and 10,000 cash. [Current as of Version 29.0]
