1.0 strategies

1. the best version is 1.8.7, since it doesn't have the bugs from 1.10.1-1.13.9 and has senna bird, it also has all episodes unlocked when you do seedway
2. most of the mods have unlimited money but don't have the rest of the episodes unlocked (before 1.8.7) or skip seedway, so it's best to find a mod that has unlimited currency and all episodes unlocked after seedway, but the chances are low
3. the best karts to use are mainly the ones that upgrade to a stronger version, however the bad ones are mainly the premium karts except for dragster snout and trash thrasher, the ones that upgrade are rocket racer, point breaker and tar barreler as well as the seasonal karts
4. the fastest route for any% is to complete seedway and stunt, you only need to do the champion chases to progress
5. target/turbo karts are the fastest karts in the game, using them with the leaf blower makes them faster, the sub zero one though can't control in the air
6. the topbar skip allows you to skip the results screen, but best used on champion chases as you save time by skipping the score counting and the rewards, yet despite giving you them
7. the best racers are always the ones that give you a speed boost: such as red, corporal pig, the blues, chuck and senna bird, bubbles and bomb

2.0 strategies

1. the best version is 2.9.1, it has broken jenga and telepods, but the servers work, 2.9.2 fixes these but the servers are gone (except the ads), it's also best used with infinite money (increases when you purchase stuff)
2. the best karts are always the ones with 300cc max
3. you can only use abilities up to 5 times, in which it grays out when you try to use more
4. the chuck and bomb glitches work best on ios, but work on android and are harder, but the weaver xt (barbequick) is extremely slow
5. for any%, the shortest route is to level up enough to buy the fastest karts, which is pretty hard at the start of the game due to the low xp counts, ng+ is only for this run as you can replay the bosses
6. try to skip ads as much as possible since they add up time but if you click them you will get to an almost infinite loop of amazon redirects (for me)
