Mobile legends Magic Chess GO GO is OP! It's fantasy RPG, based on the biggest mobile MOBA game. Matches are up to 30min. Slow pace but lots strategy (as you advance, time goes short). The play is automatic, you sort and choose everything. You'll buy heroes from the shop, upgrade them, set items, build synergies, counter- builds, and more. I've played it now for some 4 years, and they update it lots. Always something new. Atm 3 game modes.
It does consume battery a lot...10-20% on my samsung S10 per game.
