While most series on Tapas are free, some have locked episodes. Locked episodes are marked with a small lock icon, and can be unlocked with Tapas Ink, or by using free episode tickets you may have received for that series.
You can unlock one episode at a time, or unlock every available episode at once to save. Generally, the more episodes you unlock at once, the more you'll save per episode.
To unlock an episode, simply tap a locked episode from the series screen, or swipe from one episode to the next while reading.
If the next episode is locked and you don't have any free episodes remaining, you'll be given unlocking choices. The exact choices will differ depending on the number of locked episodes remaining, and whether the series is completed or ongoing.
If a series is completed, you can unlock one episode or the entire series. If a series is still ongoing, you can unlock the current episode or all currently available episodes, but will still need to unlock any additional locked episodes released in the future.
Once you've made your selection, the episode will unlock so you can continue reading. If you don't have enough Ink to unlock the episode(s) you want, you'll be taken to the Ink Shop to get more first.
"Wait for free" series
Some series are "Wait for free," which means they let you start a timer to wait and unlock episodes for free.
You may also receive free episode tickets in your Gift Box from time to time, which will let you unlock an episode of a specific series without spending any Ink.
