Here are some indoor routes I've finished at my local climbing gym. I try to go 3 or 4 days a week.

Note: It's challenging to get good photos while climbing indoors
due to a variety of factors - apologies for these so-so images.
Below: I'm doing a 5.10c route to warm up. Climbing route difficulty ratings start at 5.0 (meaning a rope is needed to climb it) and
increment numerically up to 5.9 (most people can climb at this level). Then it goes 5.10a, 5.10b, 5.10c, and 5.10d, followed by
5.11a, 5.11b, 5.11c, and 5.11d, then 5.12a ... etc. on up to 5.15. In the gym, I've never seen a route above 5.13a.
Below: This pink route is the first 5.11c I climbed
'on-sight', i.e. finishing on the first try with no 'takes'.
Below: This white route is the first 5.11d I climbed 'clean',
i.e. with no 'takes' but after previous attempts that needed 'takes'.
Below: This wall has several 5.11b routes (green, pink, yellow) I've done 'clean', and
a 5.11c (white, right side) I struggled to finish. It's a more difficult wall because it
leans out, causing more weight to hang on your hands and fingers while climbing.
Below: This wall is challenging due to its multiple angles and lean-outs. The
white 5.11c kicked my tail - I eventually got to the top, but with one 'take'.
Below: This wall has a 'roof' (shadowy area in the middle), a short section requiring
the climber to go nearly upside-down to get through. I've finished the red 5.10c,
green 5.10a, and yellow 5.10c 'clean', and previously climbed up to 5.11b on this
wall (the gym changes the routes every few weeks to keep things interesting).
Below: This white route is the first 5.11c I actually finished,
albeit with one 'take'. Later, I was able to finish it 'clean'.
Below: Alex Honnold is one of the world's top climbers, known for his incredibly
dangerous 'free solo' climbs (no ropes or safety protection of any kind - just him
and the rock) including Yosemite's Half Dome and the 3000+ foot El Capitan.
Needless to say, I don't do that!
Below: This pink route is the first 5.12a that I actually got to the top.
The best I did on it is one 'take' (briefly hang on the rope to rest).
Below: This red route is the first 5.11d I climbed 'on sight', meaning
I got to the top with no 'takes' the very first attempt. Yeee-ha!
