I start with my "favourites", which are usually long term favourites, such as Munchkins & clones, and a few of the AWP games.
I play one until I have gone down a given amount, and if it seems "dead" move on. If it seems willing, I will press on further.
If a slot is stubborn, I will play another, but eventually have another try at the stubborn one.
If I get a big hit, I play on to see whether it is still offering near misses on free spins, and if so, may press on - a bit too far sometimes. If after a big hit it seems to have changed state abruptly to "dead", it's off the list for the rest of the session.
If I hit really big, I will sometimes increase my bets, particularly on slots that have yet to offer the free spins.
I will also mess around with coin size and coins per line, keeping the bet about the same, but made up of different combinations. Absolutely NO scientific evidence to suggest it makes a difference, but it's a break from just clicking "spin" all the time
I tend not to cash out minor gains, but when I hit a decent streak, I set a floor value, and when the streak dies, and by balance falls to that value - I cash out (well, MOST of the time
).
When well ahead, I try some "mad" bets, and some new slots, or even both together. This sometimes turns a good win into a LEGEND, such as the £67.50 Munchkins bet that hit free spins on the FIRST spin at that level, and then retriggered countless times to yield over 10K (got bonus banned for that one
).
