Can someone teach me how to get a jungler to gank top lane?

• Manipulate lane to be pushed into your tower when the jungler is on your side of the map
• Call out and type times for the enemy's summoner spells, as well as when/where the enemy wards
• Ask nicely
• Hope

The best way to get a jungler top is to have good wave control. Once a wave starts pushing towards your tower, tell him in chat that it's pushing and that it will be a free kill for HIM (even if you plan on taking the kill). Junglers are greedy and will come top if they think it's a freebie.

Plus make sure you ward the river, they won't come if they think the counter gank is a possibility.

Track when and where the enemy laner wards.

Try to keep a control ward along one of the gank paths.

Let your jungler know ahead of time when the lane will be pushing towards you.

I have nothing but bad news for you.

The technique I often see from Yasuo mains is to say "I need ganks" a couple of times early in the game. and then say stuff like "enemy jungler gank X times, you gank 0 times" a bunch of times.

This technique does not appear to be effective.

how to get your jungler to gank if pinging doesn't help: step 1: tell your jungler how many times their jungler has ganked toplane. keep count and remind them constantly. step 2: wait for your blue/red buff to come up, then try to lure your opponent into the river and towards it, so they might take it, particularly if they manage to kill you. maybe your jungler might notice something now that their toplaner is a problem to them. step 3: ping MIAs on them whenever you die, especially if its to a gank. step 4: do all this while constantly shoving your lane.
