So, what’s the best way to TH?
Depends on your priorities.
If you want to clear those sixty move requirements for Campaign, basic TH strats will apply… scan from top to bottom, prioritizing five, then four matches, clear as much of the board as possible when matching to allow for cascades, etc.
Now, TH strats change if you’re resource grinding, as other forum members have suggested. It’s really contingent on where you’re at in the game.
For example, a late gamer will likely approach TH with gem sourcing in mind, as it is the most valuable resource that requires the least time investment in a TH session (green chest strat).
For an early gamer, every resource is valuable (especially keys), so perhaps matching vaults is worth the extra time and effort involved.
I approach TH valuing every resource (low-level, early player, with no guild assistance here), with a priority on creating vaults in the least amount of time (rushing vaults), while being able to end the map soon thereafter.
All those high move maps are nearly worthless if multiple vaults aren’t created, imho. If one is going to spend a substantial amount of time just to accrue a high number of moves during a map absent of multiple vaults, the net reward is really only multiple chances at arcane traitstones (which could be a strat if that’s what’s intended, I suppose).
Ultimately, your approach (and RNG) will determine what you get out of TH.
