No energy, no cooldown
DeenOD does not use an energy system. There is no battle cost, no timer, and no wait between rounds. Majlis, Sibaq, ranked Duels, Solo, Takhmin, Ta'reef, and Naqsh are all playable as much as you want, back to back, for as long as you want.
Why
Nothing in the game is paced by a timer designed to sell you a skip. The kill bar is the same one that governs everything else the studio ships: no energy timers, no FOMO loops. Play a round or play all night - the app doesn't slow you down either way.
Prayer breaks
The one thing that can pause play is a prayer time, and only if you turn Salah break on in Settings. It's an optional, gentle nudge - not a lock - and lifts the moment you tell the app you've prayed.
