A few questions for the experts.

1. You need to use world clock instead of the "Every 1 second". Take a look at the Date plugin.

2. I made a demo:

4. If the SMS Blaster doesn't provide this feature, then yes, you need to store the mobile number and the time it was last used on your own server.

Hi dop! Thanks for having you here guiding me again, thanks for the .capx on the second question, it works splendidly. But on the first question, I had a look at the date plugin's documentation which is here: construct.net/en/make-games/manuals/construct-3/plugin-reference/date

And had played around with it, but I'm not so sure on how am I able to use this to create a countdown timer. Or am I looking at the wrong plugin when you mentioned "World clock"? As even when I'm using the date plugin, I'm just converting miliseconds to minutes, but how do I get these minutes to subtract itself? At the end of the day I found out I'm still using the Every X second logic, which still makes my clock freeze.

See this demo:

Even when the game is suspended, when you resume it, the timer will "catch up".

Thanks for show me that, but I'm wondering, using the logic you had written, how is it possible to write action for it? Since by using the global variable subtract 1 action, the global variable constantly changes, and when it reaches == 0 , we can end the game. But currently, the timer counts down from 20, using milliseconds until it reaches 0. How would I go around making it if it reaches 0 the game ends? Also: Is it possible to format the countdown into a minute and seconds timer? IE: 10:00 -> 09:59.... etc, instead of using numbers such as: 600 -> 599.... Thanks!

((Date.Now-start)/1000) is the number of seconds passed since the start of countdown. You can do whatever you need with this number. For example compare if it's >=20, this means that 20 seconds has passed.

See this demo on how to format the time:

https://howtoconstructdemos.com/simple-stopwatch/

zeropad(floor(minutes - round((Date.Now-start)) / 60000 % 60),2) & ":" & zeropad(floor(seconds - round((Date.Now-start))/1000 % 60),2)

Thanks Dop! So after awhile of testing, I've decided to use the logic above, it uses 2 variable though one minutes, and another one for seconds, but it gets the job done, except that I do know it's extremely flawed. But atleast it's real-time. I am attempting to write a logic to make it so when both the seconds and minutes var = 0, it will stop the game next.

PS: Anyway I just thought of another issue that hopefully you may be able to answer me :c..

So these are the scenario:

1) My database has 10 rewards , lets call this Reward X. So these 10 rewards are loaded into my global variable through AJAX.

2) A player plays my game, and win a reward X, so i will subtract 1 from reward X, and update my database. Now my database has 9 rewards left.

3) My timer of 15minutes starts counting down, and within these 15minutes, if you do not provide me your address, the reward goes back into the pool (I'll be doing add 1, and update it through AJAX).

4) When the 15minutes timer starts counting down and you close your browser (Forcing the game to close as well), I want the reward to go back into my database as well.

^ So based on the above scenario, is it possible to do #4? Or should I rewrite my logic to make it so, I do not deduct the rewards first, but instead to detect it on the 3rd step, where if the player actually inserts their address in step 3, then only I will deduct the reward.
