TETR.IO Attack Calculator

A fan made attack calculator for the TETR.IO garbage system

Not affiliated with @o5k (osk) or TETR.IO

I learnt JavaScript just to make this so sorry if code is bad lol

Accuracy

I extrapolated the formulas for the garbage based off of osk's attack table:

Singles

According to osk the formula for singles is

Math.floor(Math.log1p(combo_level * 1.25))

General Attack Formula

Based off of the attack table, I extrapolated

Math.floor(combo_level/(4/(B2B_level + base_attack))) + B2B_level + base_attack

B2B Levels

I couldn't find a general formula for the B2B chaining formula so i just went with the one that osk said in discord:

Level	B2Bs
0	0
1	1-2
2	3-7
3	8-23
4	24-66
5	67-184
6	185-503
7	504-1369
8	1370+

Technically we don't actually know when level 8 ends but someones probably not going to get 1370+ B2Bs in a row anyways
