Spaced Whites cost more than Spaced Pinks, give the same amount of eco as Spaced Pinks, but its offensive is much heavier because it sends Whites. Amount of eco to constantly send: 214.2857 (4dp).In some rare cases, Grouped Pinks can be spammed out to rush the opponent for high offense, but by this point most defenses capable of beating large amounts of Grouped Yellows can easily beat Grouped Pinks. For simply spamming eco, this is the optimal choice, but is less efficient in cost compared to other sends such as Grouped Whites. They are the second-fastest to send (second to Grouped Purples), give a hefty amount of eco, and are forever available in the current battle once unlocked. Grouped Pinks are the basis of eco for the much later rounds. Pinks are the fastest bloon in the game, and are especially effective against defenses reliant on slow towers. Spaced Pinks are more costly than Spaced Yellows, give a little less eco than spaced yellows, are sent a little faster per slot, but are stronger in offense. Amount of eco to constantly send: 186.6667 (4dp).Against Grouped Yellows yourself, find a fast-attacking tower that also excels against grouped bloons. Grouped Yellows have exactly the same eco cost-efficiency as Grouped Greens per dollar and have a much stronger offensive value. Grouped Yellows are slightly denser than Grouped Greens and are sent much faster, and send Yellows instead of Greens. Spaced Yellows are a deadly send against towers that find it difficult to catch fast-moving bloons.

Amount of eco to constantly send: 125.2174 (4dp).Like Grouped Blues, Grouped Greens extrapolate eco hugely if spammed, but because they aren't as efficient as Grouped Blues they shouldn't always be used unless there is already a solid flow of income while also yourself defending against other rushes. Grouped Greens are slightly denser than Grouped Blues and are sent much faster, and send Greens instead of Blues. To counter Spaced Greens yourself, a tower that does more than one damage per shot will often suffice. Amount of eco to constantly send: 73.0435 (4dp)įor the lower cost than Spaced Blues, Spaced Greens are also sent faster and have a greater offensive value against towers that do not excel against spaced bloons.To beat Grouped Blues, towers that excel against grouped bloons will be even more important.
