The short version: The official Steam page says single-player works offline and co-op supports four players, while also disclosing DLC and real-money in-game items; check the exact platform and region before buying.

Source check: 3 August 2026. No hands-on review is claimed.

Players searching for Bloons TD 6 often want a practical answer before a tier list: can it be played offline, can friends join, and what else is sold after the base purchase?

The official Bloons TD 6 Steam page answers those questions more reliably than an old forum post, although the exact price, package, and feature count can change.

Offline play

Ninja Kiwi’s Steam description says that single-player offline works without Wi-Fi. That statement is narrower than “the entire game is offline.” Online co-op, shared content, cloud features, events, account services, updates, and store interactions can still require a connection.

If offline access is the deciding factor, verify the behavior on the exact device and storefront you plan to use. A Steam listing does not automatically describe every mobile or console edition.

Co-op

The same page advertises four-player co-op, meaning the player plus up to three others. It lists both public and private games.

The store description does not establish the quality of matchmaking, latency from a particular region, how progression is shared, or whether every mode is available in co-op. Those are version-specific questions to confirm through the current game documentation and recent player reports.

What the official page lists

At the source-check date, the Steam page described:

  • 25 towers with three upgrade paths;
  • 17 heroes;
  • more than 70 handcrafted maps;
  • bosses, Odysseys, Contested Territory, quests, and a content browser;
  • regular updates;
  • paid downloadable content and in-game items purchasable with real money.

These are developer/storefront statements, not Sapzy test results. Counts and packages may change after an update.

A clean purchase check

  1. Open the official listing for your platform and region.
  2. Confirm the base price, included content, DLC, and device requirements.
  3. Decide whether offline single-player satisfies the way you expect to play.
  4. If co-op matters, confirm that each participant has the required platform, account, version, and network access.
  5. Review in-app purchase controls for a shared or child-used device.
  6. Treat old feature counts as dated unless the current listing confirms them.

Primary source

Sapzy’s fit call: the official page supports offline solo play and broad co-op and content claims, but it also clearly describes continuing paid content. Buy for the modes you will actually use, not the largest feature count in a list.
