Before you open Plinko Game and start a session, decide exactly how much PKR you are willing to spend. This should come from your entertainment budget — money that has no other job to do. Think of it the same way you would a cinema ticket or a meal out.
Once that amount is gone, the session ends. Full stop. Do not top up, do not transfer from another account, do not tell yourself "just one more deposit." The budget you set in advance is the one that counts.
Use the PKR deposit limit feature in your account settings to enforce this automatically. If your weekly entertainment budget is PKR 2,000, set that as your weekly deposit limit. The platform will stop you from exceeding it even if you are tempted in the moment.
